A Unified Theory of Jetted Tidal Disruption Events: From Promptly Escaping Relativistic to Delayed Transrelativistic Jets

O Teboul, BD Metzger - The Astrophysical Journal Letters, 2023 - iopscience.iop.org
Only a tiny fraction∼ 1% of stellar tidal disruption events (TDEs) generate powerful
relativistic jets evidenced by luminous hard X-ray and radio emissions. We propose that a …

Spin-orbit angle measurements for six southern transiting planets-New insights into the dynamical origins of hot Jupiters

AHMJ Triaud, AC Cameron, D Queloz… - Astronomy & …, 2010 - aanda.org
Context. Several competing scenarios for planetary-system formation and evolution seek to
explain how hot Jupiters came to be so close to their parent stars. Most planetary …

Circumbinary accretion from finite and infinite disks

DJ Muñoz, D Lai, K Kratter… - The Astrophysical …, 2020 - iopscience.iop.org
We carry out 2D viscous hydrodynamics simulations of circumbinary disk (CBD) accretion
using AREPO. We resolve the accretion flow from a large-scale CBD down to the streamers …

The formation of low-mass binary star systems via turbulent fragmentation

SSR Offner, KM Kratter, CD Matzner… - The Astrophysical …, 2010 - iopscience.iop.org
We characterize the infall rate onto protostellar systems forming in self-gravitating radiation-

ABSTRACT OJ287 is the best candidate active galactic nucleus (AGN) for hosting a
supermassive binary black hole (SMBBH) at very close separation. We present 120 Very …

Planet hunters: A transiting circumbinary planet in a quadruple star system

ME Schwamb, JA Orosz, JA Carter… - The Astrophysical …, 2013 - iopscience.iop.org
We report the discovery and confirmation of a transiting circumbinary planet (PH1b) around
KIC 4862625, an eclipsing binary in the Kepler field. The planet was discovered by …

Tearing up the disc: misaligned accretion on to a binary

C Nixon, A King, D Price - Monthly Notices of the Royal …, 2013 - academic.oup.com
In a recent paper, we have shown that the evolution of a misaligned disc around a spinning
black hole can result in tearing the disc into many distinct planes. Tearing discs with random …
