Lecanora rhizinata spec. nova, liquen taxonómicamente aislado, sobre fisuras de rocas exfoliables, en España

Se describe una nueva especie de Lecanora Ach. (L. rhizinata Poetl., Barreno & Rico) de la alta montaña del Centro de España, que se desarrolla sobre rocas metamórficas fácilmente exfoliables. La especie puede encuadrarse dentro de la subsección Concolores Poelt (sect. Petrasterion Poelt, subgen. Placodium (Pers.) Poelt) del género Lecanora. Sin embargo, la compleja estructura anatómica del talo, en la que se diferencian fascículos de hifas fuertemente conglutinadas, que partiendo del córtex penetran hacia la médula llegando, en ocasiones, hasta el límite inferior de la escuámula e intercalándose con la capa gonidial a la que disgregan en glomérulos, unido a la presencia de cordones rizinales («Rhizinenstränge»), hacen que la nueva especie tenga una posición aislada dentro del grupo Concolores y pudiera reclamar un estatus distinto. Asimismo se hace una comparación con otras especies de la citada subsect. Concolores y con otros géneros de Lecanoraceae.

A Planetary Nebula around Nova V458 Vulpeculae Undergoing Flash Ionization

Nova V458 Vul erupted on 2007 August 8 and reached a visual magnitude of 8.1 a few days later. Ha images obtained 6 weeks before the outburst as part of the IPHAS Galactic plane survey reveal an 18th magnitude progenitor surrounded by an extended nebula. Subsequent images and spectroscopy of the nebula reveal an inner nebular knot increasing rapidly in brightness due to flash ionization by the nova event. We derive a distance of 13 kpc based on light travel time considerations, which is supported by two other distance estimation methods. The nebula has an ionized mass of 0.2 Msolar and a low expansion velocity: this rules it out as ejecta from a previous nova eruption, and is consistent with it being a ~14,000 year old planetary nebula, probably the product of a prior common envelope (CE) phase of evolution of the binary system. The large derived distance means that the mass of the erupting WD component of the binary is high. We identify two possible evolutionary scenarios, in at least one of which the system is massive enough to produce a Type Ia supernova upon merging.

Classical novae from the POINT-AGAPE microlensing survey of M31 - II. Rate and statistical characteristics of the nova population

The POINT-AGAPE (Pixel-lensing Observations with the Isaac Newton Telescope-Andromeda Galaxy Amplified Pixels Experiment) survey is an optical search for gravitational microlensing events towards the Andromeda galaxy (M31). As well as microlensing, the survey is sensitive to many different classes of variable stars and transients. In our first paper of this series, we reported the detection of 20 classical novae (CNe) observed in Sloan r' and i' passbands.

Classical novae from the POINT-AGAPE microlensing survey of M31 - I. The nova catalogue

The POINT-AGAPE (Pixel-lensing Observations with the Isaac Newton Telescope-Andromeda Galaxy Amplified Pixels Experiment) survey is an optical search for gravitational microlensing events towards the Andromeda galaxy (M31). As well as microlensing, the survey is sensitive to many different classes of variable stars and transients. Here we describe the automated detection and selection pipeline used to identify M31 classical novae (CNe) and we present the resulting catalogue of 20 CN candidates observed over three seasons. CNe are observed both in the bulge region as well as over a wide area of the M31 disc. Nine of the CNe are caught during the final rise phase and all are well sampled in at least two colours. The excellent light-curve coverage has allowed us to detect and classify CNe over a wide range of speed class, from very fast to very slow. Among the light curves is a moderately fast CN exhibiting entry into a deep transition minimum, followed by its final decline. We have also observed in detail a very slow CN which faded by only 0.01 mag d(-1) over a 150-d period. We detect other interesting variable objects, including one of the longest period and most luminous Mira variables. The CN catalogue constitutes a uniquely well-sampled and objectively-selected data set with which to study the statistical properties of CNe in M31, such as the global nova rate, the reliability of novae as standard-candle distance indicators and the dependence of the nova population on stellar environment. The findings of this statistical study will be reported in a follow-up paper.

The geometry and ionization structure of the wind in the eclipsing nova-like variables RW Tri and UX UMa

The UV spectra of nova-like variables are dominated by emission from the accretion disk, modified by scattering in a wind emanating from the disk. Here, we model the spectra of RW Tri and UX UMa, the only two eclipsing nova-like variables which have been observed with the Hubble Space Telescope in the far-ultraviolet, in an attempt to constrain the geometry and the ionization structure of their winds. Using our Monte Carlo radiative transfer code, we computed spectra for simply parameterized axisymmetric biconical outflow models and were able to find plausible models for both systems. These reproduce the primary UV resonance lines-N v, Si iv, and C iv-in the observed spectra in and out of eclipse. The distribution of these ions in the wind models is similar in both cases as is the extent of the primary scattering regions in which these lines are formed. The inferred mass-loss rates are 6%-8% of the mass accretion rates for the systems. We discuss the implication of our point models for our understanding of accretion disk winds in cataclysmic variables. © 2010. The American Astronomical Society. All rights reserved.

The Unusually Luminous Extragalactic Nova SN 2010U

We present observations of the unusual optical transient SN 2010U, including spectra taken 1.03 days to 15.3 days after maximum light that identify it as a fast and luminous Fe II type nova. Our multi-band light curve traces the fast decline (t 2 = 3.5 ± 0.3 days) from maximum light (MV = -10.2 ± 0.1 mag), placing SN 2010U in the top 0.5% of the most luminous novae ever observed. We find typical ejecta velocities of ≈1100 km s-1 and that SN 2010U shares many spectral and photometric characteristics with two other fast and luminous Fe II type novae, including Nova LMC 1991 and M31N-2007-11d. For the extreme luminosity of this nova, the maximum magnitude versus rate of decline relationship indicates a massive white dwarf (WD) progenitor with a low pre-outburst accretion rate. However, this prediction is in conflict with emerging theories of nova populations, which predict that luminous novae from massive WDs should preferentially exhibit an alternate spectral type (He/N) near maximum light.

O presente trabalho visa conhecer e caracterizar as aprendizagens promovidas pelas principais instituições da freguesia de Vila Nova de S. Bento (concelho de Serpa), avaliando a presença relativa dos contextos formais, não – formais e informais. Realizámos uma abordagem teórica, com o intuito de precisar alguns conceitos chave como aprendizagem, ambientes de aprendizagem e território. Para concretizar o trabalho empírico, e tendo como base as questões subjacentes à investigação, utilizámos uma metodologia mista (quantitativa/qualitativa) com uma aproximação conceptual ao estudo de caso. O instrumento utilizado na recolha de dados foi o inquérito por questionário aplicado. Fizemos uma recolha, análise e interpretação de dados que nos permitiram inferir:  As instituições objecto do nosso estudo constituem um potencial educativo no território analisado;  Estas instituições desenvolvem um conjunto de actividades de aprendizagem que poderão ser um recurso para o território;  Estabelecida uma relação de diálogo com a escola e outros parceiros locais, será possível potenciar novas ofertas educativas neste território. Terminámos este trabalho, com a apresentação de algumas recomendações e sugestões, que poderão vir a integrar novas investigações; ### Abstract: The present study aims to now and characterizes the learning’s promoted by the main institutions in the town of Vila Nova de S. Bento (Serpa), evaluating the relative presence of formal, non-formal and informal contexts. We made a theoretical approach, aiming to precise some key concepts, like learning ambient and territories. To realise the empiric work, and having as base subjacent questions to the investigation, we used a mixed methodology (quantitative/qualitative) as a conceptual approach to the case study. The instrument used in the recollection of data was an inquiry by applied questioner. We made a recollection, analysis and interpretation of data witch permitted as to infer:  The institutions which we observed in our study have an educative potential,  These institutions developed a series of learning activities that might be a good source for the territory,  Establishing a relationship between the school and the other local partners, it will be possible to potentiate the learning offers. We end this study by presetting some recommendations and suggestions that might be integrated in new investigations.
