Probing the composition of sub-millisecond rotating compact stars by r-modes instability
, 2012 We investigate the implications of the r-modes instability on the composition of a compact star rotating at a sub-millisecond period. In particular, the only viable astrophysical scenario for such an object, wich might present inside the Low Mass X-ray ...

A Search for Gravitational Waves from Perturbed Black Hole Ringdowns in LIGO Data [PDF]
, 2008 According to General Relativity a perturbed black hole will return to a stable configuration by the emission of gravitational radiation in a superposition of quasi-normal modes. Such a perturbation will occur due to the coalescence of a black hole binary,

False-positive Self-lensing Events: TESS Observing Asteroid-crossing Events in Disguise
The Astrophysical Journal, 2023 We report observations of four asteroid-crossing events in Transiting Exoplanet Survey Satellite light curves masquerading as self-lensing pulses from binary systems containing main-sequence stars and black hole or neutron-star companions.

Compact stars and the evolution of binary systems [PDF]
, 2011 The Chandrasekhar limit is of key importance for the evolution of whitedwarfs in binary systems and for the formation of neutron stars and black holes in binaries.Mass transfer can drive a white dwarf in a binary over the Chandrasekhar limit,which may lead to a Type Ia supernova (in case of a CO white dwarf) or an Accretion-Induced Collapse (AIC, in ...

Neutrino treatment in multidimensional astrophysical simulations : a new spectral scheme [PDF]
, 2014 Neutrinos play a central role in modern physics and astrophysics. Their extremely weak interaction rate with baryons and other leptons makes their detection on the Earth difficult and challenging.

Electromagnetic Characterization of the LISA Verification Binary ZTF J0526+5934
The Astrophysical Journal, 2023 We present an analysis of new and archival data to the 20.506 minute LISA verification binary J052610.42+593445.32 (J0526+5934). Our joint spectroscopic and photometric analysis finds that the binary contains an unseen M _1 = 0.89 ± 0.11 M _⊙ CO-core ...

On the angular momentum transfer on to compact stars in binary systems [PDF]
Monthly Notices of the Royal Astronomical Society, 2001 Results of three-dimensional numerical simulations of the gas transfer in close binary systems show that, in addition to the formation of a tidally induced spiral shock wave, it is also possible for accretion streams to be produced, having low specific angular momentum in a region close to the accreting star.
