X-Ray, UV, and Optical Observations of Proxima Centauri's Stellar Cycle
B. J. Wargelin, S. H. Saar, Z. A. Irving +3
Proxima Cen (GJ 551; dM5.5e) is one of only about a dozen fully convective stars known to have a stellar cycle, and the only one to have long-term X-ray monitoring. A previous anal…
X-Ray Flaring on the dMe Star, Ross 154
B. J. Wargelin, V. L. Kashyap, J. J. Drake +2
We present results from two Chandra imaging observations of Ross 154, a nearby flaring M dwarf star. During a 61-ks ACIS-S exposure, a very large flare occurred (the equivalent of…
Doppler Shifts and Broadening and the Structure of the X-ray Emission from Algol
Sun Mi Chung, Jeremy J. Drake, Vinay L. Kashyap +2
In a study of Chandra High Energy Transmission Grating spectra of Algol, we clearly detect Doppler shifts caused by the orbital motion of Algol B. These data provide the first defi…
