  1. Super-Eddington Chimneys: On the Cooling Evolution of Tidal Disruption Event Envelopes

    Publication
    The formation of a compact accretion disk following a tidal disruption event (TDE) requires that the shocked stellar debris cool efficiently as it settles toward the black hole …

  2. The Rise of the Black Hole X-Ray Binary AT 2019wey Observed with TESS

    Publication
    Black hole X-ray binaries (BHXRBs) have traditionally been discovered by X-ray surveys with cadences of hours to days. However, large optical time-domain surveys now provide …

  3. Fading into Darkness: A Weak Mass Ejection and Low-efficiency Fallback Accompanying Black Hole Formation in M31-2014-DS1

    Publication
    Stellar-mass black holes (BHs) can form from the near-complete collapse of massive stars, causing them to abruptly disappear. The star M31-2014-DS1 in the Andromeda …

  4. Disappearance of a massive star in the Andromeda Galaxy due to formation of a black hole

    Publication
    When a massive star reaches the end of its lifetime, its core collapses and releases neutrinos that drive a shock into the outer layers (stellar envelope). A sufficiently …

  5. Radiation Hydrodynamic Simulations of Low-Energy Explosions of Red and Yellow Supergiants

    Publication
    A variety of physical processes leads to the low-energy ejection of material from the hydrogen-rich envelopes of red and yellow supergiants. These include common envelope events …
