A Comprehensive X-ray Report on AT2019wey
Yuhan Yao, S. R. Kulkarni, K. C. Gendreau +25
Here, we present MAXI, SWIFT, NICER, NuSTAR and Chandra observations of the X-ray transient AT2019wey (SRGA J043520.9+552226, SRGE J043523.3+552234). From spectral and timing analy…
Surveying the X-ray Behavior of Novae as They Emit -rays
Alexa C. Gordon, Elias Aydi, Kim L. Page +5
The detection of GeV -ray emission from Galactic novae by -LAT has become routine since 2010, and is generally associated with shocks internal to the nova ejecta. These s…
Increasing activity in T CrB suggests nova eruption is impending
Gerardo J. M. Luna, J. L. Sokoloski, K. Mukai +1
Estimates of the accretion rate in symbiotic recurrent novae (RNe) often fall short of theoretical expectations by orders of magnitude. This apparent discrepancy can be resolved if…
Measuring the masses of magnetic white dwarfs: A NuSTAR Legacy Survey
A. W. Shaw, C. O. Heinke, K. Mukai +11
The hard X-ray spectrum of magnetic cataclysmic variables can be modelled to provide a measurement of white dwarf mass. This method is complementary to radial velocity measurements…
X-ray Spectroscopy of the gamma-ray Brightest Nova V906 Car (ASASSN-18fv)
Kirill V. Sokolovsky, Koji Mukai, Laura Chomiuk +15
Shocks in gamma-ray emitting classical novae are expected to produce bright thermal and non-thermal X-rays. We test this prediction with simultaneous NuSTAR and Fermi/LAT observati…
X-ray evolution of the nova V959 Mon suggests a delayed ejection and a non-radiative shock
Thomas Nelson, Koji Mukai, Laura Chomiuk +7
X-ray observations of shocked gas in novae can provide a useful probe of the dynamics of the ejecta. Here we report on X-ray observations of the nova V959 Mon, which was also detec…
