Eberstadt-Seligmann Family Collection 1772-1885

Family tree; six original family letters dealing with private affairs.

Ehrenberg-Rosenzweig Family Collection 1772-1930

The collection contains correspondence among members of the Ehrenberg and Rosenzweig families, including letters from Franz Rosenzweig, Adam Rosenzweig and Richard Ehrenberg, as well as with other parties, including Leopold Zunz, Adelheid Zunz, Claire von Gluemer, and Heinrich Heine (copies only). Also included are engagement contracts, marriage banns, school curricula and certificates, character references, eulogies, family histories, and other documents concerning family members. This material also reflects much of the history of the Samsonschule in Wolfenbuettel of which members of the Ehrenberg family were principals.

Temple Emanuel (Andover, Mass.) records, 1939-2001; and Part II (addendum), undated 1952-2004

Temple Emanuel was founded in 1920 in Lawrence, Massachusetts. It began by serving a small immigrant Jewish community that has since grown to an affluent and lively congregation of about 600 families. This growth occurred largely under the tenure of Rabbi Harry A. Roth, who lead the congregation from 1962 until 1990 and oversaw the temple’s move to Andover, Massachusetts. This collection includes correspondence, photographs, and sermons.

YSOVAR: Mid-infrared Variability in the Star-forming Region Lynds 1688

The emission from young stellar objects (YSOs) in the mid-infrared (mid-IR) is dominated by the inner rim of their circumstellar disks. We present IR data from the Young Stellar Object VARiability (YSOVAR) survey of ~800 objects in the direction of the Lynds 1688 (L1688) star-forming region over four visibility windows spanning 1.6 yr using the Spitzer Space Telescope in its warm mission phase. Among all light curves, 57 sources are cluster members identified based on their spectral energy distribution and X-ray emission. Almost all cluster members show significant variability. The amplitude of the variability is larger in more embedded YSOs. Ten out of 57 cluster members have periodic variations in the light curves with periods typically between three and seven days, but even for those sources, significant variability in addition to the periodic signal can be seen. No period is stable over 1.6 yr. Nonperiodic light curves often still show a preferred timescale of variability that is longer for more embedded sources. About half of all sources exhibit redder colors in a fainter state. This is compatible with time-variable absorption toward the YSO. The other half becomes bluer when fainter. These colors can only be explained with significant changes in the structure of the inner disk. No relation between mid-IR variability and stellar effective temperature or X-ray spectrum is found.
