Tidal disruption events
The concept of stars being tidally ripped apart and consumed by a massive black hole
(MBH) lurking in the center of a galaxy first captivated theorists in the late 1970s. The …

[HTML][HTML] Tidal disruption of stars by supermassive black holes: Status of observations
S Komossa - Journal of High Energy Astrophysics, 2015 - Elsevier
Stars in the immediate vicinity of supermassive black holes (SMBHs) can be ripped apart by
the tidal forces of the black hole. The subsequent accretion of the stellar material causes a …

Hot subluminous stars
U Heber - Publications of the Astronomical Society of the Pacific, 2016 - iopscience.iop.org
Hot subluminous stars of spectral type B and O are core helium-burning stars at the blue end
of the horizontal branch or have evolved even beyond that stage. Most hot subdwarf stars …

Repeating tidal disruptions in GSN 069: Long-term evolution and constraints on quasi-periodic eruptions' models
Context. GSN 069 is the first galactic nucleus where quasi-periodic eruptions (QPEs) have
been identified in December 2018. These are high-amplitude, soft X-ray bursts recurring …

A continuum of H-to He-rich tidal disruption candidates with a preference for E+ A galaxies
We present the results of a Palomar Transient Factory (PTF) archival search for blue
transients that lie in the magnitude range between" normal" core-collapse and …

Disk formation versus disk accretion—what powers tidal disruption events?
ABSTRACT A tidal disruption event (TDE) takes place when a star passes near enough to a
massive black hole to be disrupted. About half the star's matter is given elliptical trajectories …

X-ray quasi-periodic eruptions driven by star–disk collisions: application to GSN069 and probing the spin of massive black holes
X-ray quasi-periodic eruptions (QPEs) were discovered recently in active galaxies with an
unknown driving mechanism. Under the assumption that QPEs are caused by star–disk …

Circularization of tidally disrupted stars around spinning supermassive black holes
We study the circularization of tidally disrupted stars on bound orbits around spinning
supermassive black holes by performing 3D smoothed particle hydrodynamic simulations …

Alive but Barely Kicking: News from 3+ yr of Swift and XMM-Newton X-Ray Monitoring of Quasiperiodic Eruptions from eRO-QPE1
Quasiperiodic eruptions (QPEs) represent a novel class of extragalactic X-ray transients that
are known to repeat at roughly regular intervals of a few hours to days. Their underlying …
