Star-Disk Collisions II: Debris Stream Dynamics and Implications for QPEs and Other Transients Near SMBHs
Philippe Z. Yao, Eliot Quataert, Yan-Fei Jiang +1
Quasi-periodic eruptions (QPEs) are repeating soft X-ray nuclear transients with recurrence times of hours-days and flare duty cycles of 10-20%. Many aspects of QPEs can be m…
A positive period derivative in the quasi-periodic eruptions of ZTF19acnskyy
Joheen Chakraborty, Saul A. Rappaport, Riccardo Arcodia +9
We report the first direct measurement of the period derivative in a quasi-periodic eruption (QPE), finding a smoothly increasing period with $\dot{P}\approx (1.7\pm 0.02)\times10^…
Mass Transfer in Tidally Heated Stars Orbiting Massive Black Holes and Implications for Repeating Nuclear Transients
Philippe Z. Yao, Eliot Quataert
The structure of stars orbiting close to supermassive black holes (SMBHs) can be dramatically modified by tidal heating, which can in principle dissipate an energy much larger than…
Expansion properties of the young supernova type Iax remnant Pa 30 revealed
Tim Cunningham, Ilaria Caiazzo, Nikolaus Z. Prusinski +14
The recently discovered Pa 30 nebula, the putative type Iax supernova remnant associated with the historical supernova of 1181 AD, shows puzzling characteristics that make it uniqu…
Star-Disk Collisions: Implications for Quasi-periodic Eruptions and Other Transients Near Supermassive Black Holes
Philippe Z. Yao, Eliot Quataert, Yan-Fei Jiang +2
We use Athena++ to study the hydrodynamics of repeated star-accretion disk collisions close to supermassive black holes, and discuss their implications for the origin of quasi-peri…
The Origin of the Consistent Planetary Nebula Luminosity Function Bright-end Cutoff
Philippe Z. Yao, Eliot Quataert
The [O III] 5007 Angstrom line is typically the brightest line in planetary nebula (PN) spectra. Observations show that the brightest [O III] 5007 Angstrom PN in a galaxy -- the pl…
Negative Lags on the Viscous Timescale in Quasar Photometry and Prospects for Detecting More with LSST
Amy Secunda, Jenny E. Greene, Yan-Fei Jiang +2
The variability of quasar light curves can be used to study the structure of quasar accretion disks. For example, continuum reverberation mapping uses delays between variability in…
Observational Signatures of Carbon-Oxygen White Dwarf Merger Remnants
Philippe Z. Yao, Eliot Quataert, Andy Goulding
Many double white dwarf (WD) mergers likely do not lead to a prompt thermonuclear explosion. We investigate the prospects for observationally detecting the surviving remnants of su…
A Negative Long Lag from the Optical to the UV Continuum in Fairall 9
Philippe Z. Yao, Amy Secunda, Yan-Fei Jiang +2
We report the detection of a long-timescale negative lag, where the blue bands lag the red bands, in the nearby Seyfert 1 galaxy Fairall 9. Active Galactic Nuclei (AGN) light curve…
Radiation GRMHD simulations of M87: funnel properties and prospects for gap acceleration
Philippe Z. Yao, Jason Dexter, Alexander Y. Chen +2
We use the public code ebhlight to carry out 3D radiative general relativistic magnetohydrodynamics (GRMHD) simulations of accretion onto the supermassive black hole in M87. The si…
