The fossil wind structures of Eta Carinae: changes across on 5.54-year cycle
Theodore R. Gull, Thomas I. Madura, Mairan Teodoro +11
Eta Carinae, the closest, active, massive binary containing a highly unstable LBV, exhibits expanding, compressed wind shells, seen in emission, that are spatially and spectrally r…
STROBE-X: X-ray Timing and Spectroscopy on Dynamical Timescales from Microseconds to Years
Paul S. Ray, Zaven Arzoumanian, David Ballantyne +155
We present the Spectroscopic Time-Resolving Observatory for Broadband Energy X-rays (STROBE-X), a probe-class mission concept selected for study by NASA. It combines huge collectin…
Cosmic Ray Acceleration by Stellar Associations? The Case of Cygnus OB2
Yousaf Butt, Paula Benaglia, Jorge Combi +10
The origins of all extra-solar cosmic rays -- both the ultra high-energy and lower energy Galactic variety -- remain unclear. It has been argued that the large scale shocks and tur…
Addressing Outstanding Problems in the Physics of Massive Stars with the Line Emission Mapper X-ray Probe
Jeremy J. Drake, David Cohen, Michael Corcoran +5
We present some of the salient aspects of the scientific motivation for high resolution soft X-ray spectroscopy of early-type stars with the Line Emission Mapper X-ray Probe. The m…
CO, Water, and Possible Methanol in Eta Carinae Approaching Periastron
Patrick W. Morris, Steven B. Charnley, Michael Corcoran +12
In circumstellar gas, the complex organic molecule methanol has been found almost exclusively around young stellar objects, and is thus regarded as a signpost of recent star format…
CHANDRA/VLA Follow-up of TeV J2032+4131, the Only Unidentified TeV Gamma-ray Source
Yousaf Butt, Paula Benaglia, Jorge Combi +10
The HEGRA Cherenkov telescope array group recently reported a steady and extended unidentified TeV gamma-ray source lying at the outskirts of Cygnus OB2. This is the most massive s…
