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…
Delayed Radio Flares in Tidal Disruption Events from Star-Disk Collision Outflows
Itai Linial, Brian D. Metzger, Andrei M. Beloborodov
A growing fraction of tidal disruption events (TDEs) exhibit radio emission that rises only years after the optical or infrared flare, indicating delayed outflow activity. In some…
Even a precessing clock is right twice per orbit -- The super-periods of eRO-QPE2 and challenges for quasi-periodic eruption orbital models
R. Arcodia, G. Miniutti, J. Chakraborty +25
We present OC (``observed minus calculated'') timing analysis of the quasi-periodic eruption (QPE) source eRO-QPE2 with a multi-mission X-ray campaign, which includes 32 observe…
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^…
SN 2019vxm: A Shocking Coincidence between Fermi and TESS
Zachary G. Lane, Ryan Ridden-Harper, Sofia Rest +37
Shock breakout and, in some cases, jet-driven high-energy emission are increasingly recognized as key signatures of the earliest phases of core-collapse supernovae, especially in T…
Wind-mediated Eddington-limited emission in a Black Hole Tidal Disruption Event
Paola Martire, Elena Maria Rossi, Nicholas Chamberlain Stone +3
Observations of tidal disruption events (TDEs) have already produced tens of strong candidate flares, and their number will greatly increase with upcoming wide field surveys. Never…
