Spectroscopic Monitoring of Metal Lines in Polluted White Dwarfs
Laura K. Rogers, Michael M. Shara, Amy Bonsor +12
The disruption and accretion of planetary material onto white dwarfs is expected to be inherently dynamic and stochastic, potentially driving variability in the accretion rate and…
A Deep Precursor-Dip-Main Superoutburst Sequence in VW Hydri Observed with TESS: High-Cadence Constraints on the Thermal-Tidal Instability Model
Bisi Bernard Ogunwale, Shara Michael, Avi Shporer +2
We present 120s cadence TESS observations of three superoutbursts of the SU UMa-type dwarf nova VW Hydri. Two events (SO2 in Sectors 87+88 and SO3 in Sector 93) exhibit a pronounce…
FQ Circini: An Ordinary Nova with a High-mass B1 V(n)(e) Companion Whose Decretion Disk Transfers Mass to the White Dwarf via Roche-Lobe Overflow
Bradley E. Schaefer, Andrew Pearce, Tom Love +4
FQ Cir was an ordinary fast He/N classical nova, peaking at =10.9. The pre-eruption and post-eruption counterpart was at =14.0, making the smallest known classical nova ampli…
A multiwavelength study of the Galactic center black hole candidate MAXI J1744-294
Shifra Mandel, Kaya Mori, Paul A. Draghis +37
For the first time in nearly a decade, a bright transient was detected in the central parsec (pc) of the Galaxy. MAXI J1744-294, or -- as it was known in its previous life -- Swift…
The cosmic web's Lyman- glow at ; hydrodynamic models, dust, and wide-field, narrow-band detection
Oleksii Sokoliuk, John K. Webb, Kenneth M. Lanzetta +12
The diffuse Lyman- glow of the cosmic web has long been predicted but has so far eluded direct detection over cosmologically significant volumes. We construct synthetic Lyman-$…
A 70 pc-Diameter Nova Super-remnant Surrounding the Recurrent Nova RS Ophiuchi
Michael M. Shara, Kenneth M. Lanzetta, Alexandra Masegian +9
Recurrent novae undergo thermonuclear-powered eruptions separated by less than 100 years, enabled by subgiant or red giant donors transferring hydrogen-rich matter at very high rat…
