Bayesian Modeling of NICER Cometary X-ray Spectra: A Legacy Survey of Solar-Wind Charge Exchange
T. K. Deskins, Dennis Bodewits, Steven Bromley +3
We present a uniform, epoch-resolved analysis of soft X-ray observations of eight comets obtained with NICER, using Bayesian statistics to identify charge-exchange line components,…
Determination of the Solar System contribution to the soft X-ray sky
K. Dennerl, G. Ponti, X. Zheng +4
Solar wind charged particles interact with diffuse gas within the heliosphere, producing soft X-rays. This solar wind charge exchange (SWCX) process produces foreground emission th…
Low-mass stars dominate the hot (0.7 keV) Galactic X-ray emission
G. Ponti, M. C. H. Yeung, G. Stel +12
The circumgalactic medium (CGM) of the Milky Way is composed of a tenuous atmosphere filled with multi-phase plasma, including a warm-hot virialised component. Recent studies sugge…
First Resolution of a Main Sequence G-Star Astrosphere Using Chandra
C. M. Lisse, S. J. Wolk, B. Snios +24
We report resolution of a halo of X-ray line emission surrounding the Zero Age Main Sequence (ZAMS) G8.5V star HD 61005 by Chandra ACIS-S. Located only 36.4 pc distant, HD 61005 is…
Searching the non-accreting white dwarf population in eROSITA data
S. Friedrich, C. Maitra, K. Dennerl +3
eROSITA is the soft X-ray instrument aboard the Spectrum Roentgen Gamma (SRG) satellite that is most sensitive in the energy range between 0.2 and 2.3 keV. Between December 2019 an…
An accretion model for the anomalous X-ray pulsar 4U 0142+61
J. E. Truemper, K. Dennerl, N. D. Kylafis +2
We propose that the quiescent emission of AXPs/SGRs is powered by accretion from a fallback disk, requiring magnetic dipole fields in the range 10^{12}-10^{13} G, and that the lumi…
Chandra's Close Encounter with the Disintegrating Comets 73P/2006 (Schwassmann--Wachmann--3) Fragment B and C/1999 S4 (LINEAR)
Scott J. Wolk, C. M. Lisse, D. Bodewits +2
On May 23, 2006 we used the ACIS-S instrument on the Chandra X-ray Observatory (CXO) to study the X-ray emission from the B fragment of comet 73P/2006 (Schwassmann-Wachmann 3) (73P…
