Mass Transport Processes and their Roles in the Formation, Structure, and Evolution of Stars and Stellar Systems
Kenneth G. Carpenter, Margarita Karovska, Carolus J. Schrijver +15
We summarize some of the compelling new scientific opportunities for understanding stars and stellar systems that can be enabled by sub-mas angular resolution, UV/Optical spectral…
Massive Star Multiplicity: The Cepheid W Sgr
Nancy Remage Evans, Derck Massa, Charles Proffitt
We have obtained spectra of the W Sgr system with the STIS spectrograph on the Hubble Space Telescope. The spectra resolve the system into a distant companion B which is the hottes…
The X-Ray Environment During the Epoch of Terrestrial Planet Formation: Chandra Observations of h Persei
Thayne Currie, Nancy Remage Evans, Brad Spitzbart +5
We describe Chandra/ACIS-I observations of the massive ~ 13--14 Myr-old cluster, h Persei, part of the famous Double Cluster (h and chi Persei) in Perseus. Combining the list of Ch…
Welcome back, Polaris the Cepheid
H. Bruntt, A. J. Penny, D. Stello +2
For about 100 years the amplitude of the 4-day pulsation in Polaris has decreased. We present new results showing a significant increase in the amplitude based on 4.5 years of cont…
Direct Detection of the Close Companion of Polaris with the Hubble Space Telescope
Nancy Remage Evans, Gail H. Schaefer, Howard E. Bond +5
Polaris, the nearest and brightest classical Cepheid, is a single-lined spectroscopic binary with an orbital period of 30 years. Using the High Resolution Channel of the Advanced C…
X-Atlas: An Online Archive of Chandra's Stellar High Energy Transmission Gratings Observations
Owen W. Westbrook, Nancy Remage Evans, Scott J. Wolk +6
The high-resolution X-ray spectroscopy made possible by the 1999 deployment of the Chandra X-ray Observatory has revolutionized our understanding of stellar X-ray emission. Many pu…
