The pulsating DA white dwarf star EC 14012-1446: results from four epochs of time-resolved photometry
G. Handler, E. Romero-Colmenero, J. L. Provencal +4
The pulsating DA white dwarfs are the coolest degenerate stars that undergo self-driven oscillations. Understanding their interior structure will help to understand the previous ev…
Near-infrared Study of the Carina Nebula
Kaushar Sanchawala, Wen-Ping Chen, Devendra Ojha +6
We have carried out near-infrared (NIR) imaging observations of the Carina Nebula for an area of ~400 sq. arcmin. including the star clusters Trumpler 14 (Tr 14) and Trumpler 16 (T…
Triggered Star Formation in OB Associations
W. P. Chen, H. T. Lee, K. Sanchawala
We present causal and positional evidence of triggered star formation in bright-rimmed clouds in OB associations, e.g., Ori OB1, and Lac OB1, by photoionization. The triggering pro…
Whole Earth Telescope observations of the pulsating subdwarf B star PG 0014+067
M. Vuckovic, S. D. Kawaler
PG 0014+067 is one of the most promising pulsating subdwarf B stars for seismic analysis, as it has a rich pulsation spectrum. The richness of its pulsations, however, poses a fund…
X-ray Emitting Young Stars in the Carina Nebula
Kaushar Sanchawala, Wen-Ping Chen, Hsu-Tai Lee +5
We present a multiwavelength study of the central part of the Carina Nebula, including Trumpler 16 and part of Trumpler 14. Analysis of the Chandra X-ray Observatory archival data…
Contact Binary Variables as X-ray Sources
W. P. Chen, Kaushar Sanchawala, M. C. Chiou
We present cross-identification of archived X-ray point sources with W UMa variable stars found in the All-Sky Automated Survey (ASAS). In a surveyed sky area of 300 square degrees…
