Molecules in the disk orbiting the twin young suns of V4046 Sgr
Joel H. Kastner, B. Zuckerman, Pierre Hily-Blant +1
We report the results of a mm-wave molecular line survey of the nearby (D ~ 70 pc), 12 Myr-old system V4046 Sgr -- a tight (9 R_sun separation), short-period (2.42 day) binary with…
Identification of the TW Hya Association member 2M123539: a tertiary component of the HR 4796 system
Joel H. Kastner, B. Zuckerman, M. Bessell
The association of the late-type star 2MASS J12354893-3950245 (2M1235-39) with a bright X-ray source detected serendipitously by ROSAT and XMM-Newton, combined with its proximity t…
The X-Ray Spectrum of a Planetary Nebula at High Resolution: Chandra Gratings Spectroscopy of BD+30 3639
Young Sam Yu, Raanan Nordon, Joel H. Kastner +3
We present the results of the first X-ray gratings spectroscopy observations of a planetary nebula (PN), the X-ray-bright, young BD+30 3639. We observed BD+30 3639 for a total of 3…
Molecules in the Circumstellar Disk Orbiting BP Piscium
Joel H. Kastner, B. Zuckerman, Thierry Forveille
BP Psc is a puzzling late-type, emission-line field star with large infrared excess. The star is encircled and enshrouded by a nearly edge-on, dust circumstellar disk, and displays…
Spatially-resolved Chandra Imaging Spectroscopy of the classical/weak-lined T Tauri system V710 Tau
Sonali J. Shukla, David A. Weintraub, Joel H. Kastner
We present spatially-resolved X-ray observations of the binary T Tauri star system V710 Tau. Using Chandra's Advanced CCD Imaging Spectrometer (ACIS), we imaged this 3.2'' separati…
Gas and Dust Associated with the Strange, Isolated, Star BP Piscium
B. Zuckerman, C. Melis, Inseok Song +15
We have carried out a multiwavelength observational campaign demonstrating some of the remarkable properties of the infrared-bright variable star BP Psc. Surrounded by a compact du…
