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…
The Angular Separation of the Components of the Cepheid AW Per
D. Massa, N. R. Evans
The 6.4 day classical Cepheid AW Per is a spectroscopic binary with a period of 40 years. Analyzing the centroids of HST/STIS spectra obtained in November 2001, we have determined…
Polaris: Mass and Multiplicity
Nancy Remage Evans, Gail Schaefer, Howard E. Bond +9
Polaris, the nearest and brightest classical Cepheid, is a member of at least a triple system. It has a wide () physical companion, the F-type dwarf Polaris B. Polaris itself…
