Lense-Thirring Precession and QPOs in Low Mass X-Ray Binaries
Luigi Stella,Mario Vietri +1 more
TL;DR: The relativistic dragging of inertial frames around fast rotating collapsed stars is substantial and can give rise to observable effects as mentioned in this paper, which can be applied to the kHz quasi periodic oscillations (QPOs) sources, low mass X-ray binaries (LMXRBs) containing an accreting neutron star.
Journal ArticleDOI
Swings between rotation and accretion power in a binary millisecond pulsar
Alessandro Papitto,Carlo Ferrigno,Enrico Bozzo,Nanda Rea,Lucia Pavan,Luciano Burderi,M. Burgay,Sergio Campana,T. Di Salvo,Maurizio Falanga,Miroslav Filipovic,Paulo C. C. Freire,Jason W. T. Hessels,Jason W. T. Hessels,A. Possenti,Scott M. Ransom,Alessandro Riggio,P. Romano,John Sarkissian,Ingrid H. Stairs,Luigi Stella,Diego F. Torres,Diego F. Torres,M. H. Wieringa,Graeme F Wong,Graeme F Wong +25 more
TL;DR: Observations of accretion-powered, millisecond X-ray pulsations from a neutron star previously seen as a rotation- powered radio pulsar show the evolutionary link between accretion and rotation-powered millisecond pulsars, but also that some systems can swing between the two states on very short timescales.
Journal ArticleDOI
An enigmatic long-lasting γ-ray burst not accompanied by a bright supernova
M. Della Valle,G. Chincarini,G. Chincarini,Nino Panagia,Gianpiero Tagliaferri,D. Malesani,Vincenzo Testa,D. Fugazza,D. Fugazza,Sergio Campana,Stefano Covino,Vanessa Mangano,L. A. Antonelli,P. D'Avanzo,Kevin Hurley,I. F. Mirabel,L J Pellizza,Silvia Piranomonte,Luigi Stella +18 more
TL;DR: In this paper, deep optical observations of GRB 060614 showed no emerging supernova with absolute visual magnitude brighter than M(V) = -13.7, indicating that any supernova associated with GRB060614 was at least 100 times fainter, at optical wavelengths, than the other supernovae associated withGRBs.
Journal ArticleDOI
An accreting pulsar with extreme properties drives an ultraluminous x-ray source in NGC 5907

TL;DR: Observations showing that NGC 5907 ULX is instead an x-ray accreting neutron star (NS) with a spin period evolving from 1.43 seconds in 2003 to 1.13 seconds in 2014 suggest that other extreme ULXs (x-ray luminosity ≥ 1041 erg second−1) might harbor NSs.
Journal ArticleDOI
Correlations in the QPO Frequencies of Low Mass X-Ray Binaries and the Relativistic Precession Model
TL;DR: In this article, the relativistic precession model has been used to interpret the frequencies of quasi periodic oscillations (QPOs) from low mass X-ray binaries of the Atoll and Z classes.
