Beyond Caustic Crossings: Properties of Binary Microlensing Light Curves
Christopher Night, Rosanne Di Stefano, Megan Schwamb
Binary microlensing light curves have a variety of morphologies. Many are indistinguishable from point lens light curves. Of those that deviate from the point lens form, caustic cr…
Discovery of an eclipsing X-ray binary with a 32.69 hour period in M101: an analog of Her X-1 or LMC X-4?
Jifeng Liu, Rosanne di Stefano, Jeffrey McClintock +3
We report the discovery of an eclipsing X-ray binary in M101, the first such system to be discovered outside the Local Group. Based on a sequence of 25 Chandra observations that sa…
Supersoft X-ray sources in M31: II. ROSAT-detected supersoft sources in the ROSAT, Chandra and XMM eras
J. Greiner, R. DiStefano, A. Kong +1
We have performed Chandra observations during the past 3 years of 5 of the M31 supersoft X-ray sources (SSS) discovered with ROSAT. Surprisingly, only one of these sources has been…
The Ultraluminous X-ray Source NGC 1313 X-2 (MS 0317.7-6647) and its Environment
L. Zampieri, P. Mucciarelli, R. Falomo +5
We present new optical and {\it Chandra} observations of the field containing the ultraluminous X-ray source NGC 1313 X-2. On an ESO 3.6 m image, the {\it Chandra} error box embrac…
Supersoft X-ray Sources in M31: I. A Chandra Survey and an Extension to Quasisoft Sources
R. Di Stefano, A. K. H. Kong, J. Greiner +9
We report on very soft X-ray sources (VSSs) in M31. In a survey which was most sensitive to soft sources in four 8'x8' regions covered by Chandra's ACIS-S S3 CCD, we find 33 VSSs t…
A Synoptic X-ray Study of M31 with the Chandra-HRC
Benjamin F. Williams, Michael R. Garcia, Albert K. H. Kong +4
We have obtained 17 epochs of Chandra High Resolution Camera (HRC) snapshot images, each covering most of the M31 disk. The data cover a total baseline of 2.5 years and contain a m…
