Limits on thermal variations in a dozen quiescent neutron stars over a decade
Arash Bahramian, Craig O. Heinke, Nathalie Degenaar +5
In quiescent low-mass X-ray binaries (qLMXBs) containing neutron stars, the origin of the thermal X-ray component may be either release of heat from the core of the neutron star, o…
SN 2005ip: A Luminous Type IIn Supernova Emerging from a Dense Circumstellar Medium as Revealed by X-Ray Observations
Satoru Katsuda, Keiichi Maeda, Takaya Nozawa +2
We report on X-ray spectral evolution of the nearby Type IIn supernova (SN) 2005ip, based on Chandra and Swift observations covering from ~1 to 6 years after the explosion. X-ray s…
Discovery of the Third Transient X-ray Binary in the Galactic Globular Cluster Terzan 5
Arash Bahramian, Craig O. Heinke, Gregory R. Sivakoff +7
We report and study the outburst of a new transient X-ray binary (XRB) in Terzan 5, the third detected in this globular cluster, Swift J174805.3-244637 or Terzan 5 X-3. We find cle…
The neutron star transient and millisecond pulsar in M28: from sub-luminous accretion to rotation-powered quiescence
Manuel Linares, Arash Bahramian, Craig Heinke +6
The X-ray transient IGR J18245-2452 in the globular cluster M28 contains the first neutron star (NS) seen to switch between rotation-powered and accretion-powered pulsations. We an…
Electron Cooling in a Young Radio Supernova: SN 2012aw
Naveen Yadav, Alak Ray, Sayan Chakraborti +8
We present the radio observations and modeling of an optically bright Type II-P supernova (SN), SN 2012aw which exploded in the nearby galaxy Messier 95 (M95) at a distance of $10\…
Continued Neutron Star Crust Cooling of the 11 Hz X-Ray Pulsar in Terzan 5: A Challenge to Heating and Cooling Models?
N. Degenaar, R. Wijnands, E. F. Brown +8
The transient neutron star low-mass X-ray binary and 11 Hz X-ray pulsar IGR J17480-2446 in the globular cluster Terzan 5 exhibited an 11-week accretion outburst in 2010. Chandra ob…
The progenitor of SN 2011ja: Clues from circumstellar interaction
Sayan Chakraborti, Alak Ray, Randall Smith +7
Massive stars, possibly red supergiants, which retain extended hydrogen envelopes until core collapse, produce Type II Plateau (IIP) supernovae. The ejecta from these explosions sh…
Self-shielding of Soft X-rays in SN Ia Progenitors
J. Craig Wheeler, David A. Pooley
There are insufficient super soft (~ 0.1 keV) X-ray sources in either spiral or elliptical galaxies to account for the rate of explosion of Type Ia supernovae in either the single…
A superburst candidate in EXO 1745--248 as a challenge to thermonuclear ignition models
D. Altamirano, L. Keek, A. Cumming +6
We report on Chandra, RXTE, Swift/BAT and MAXI observations of a ~1 day X-ray flare and subsequent outburst of a transient X-ray source observed in October-November 2011 in the glo…
X-Ray emission from SN 2004dj: A Tale of Two Shocks
Sayan Chakraborti, Naveen Yadav, Alak Ray +2
Type IIP (Plateau) Supernovae are the most commonly observed variety of core collapse events. They have been detected in a wide range of wavelengths from radio, through optical to…
