GRB 130603B: No Compelling Evidence for Neutron Star Merger [PDF]
Advances in Astronomy, 2015 The near infrared (NIR) flare/rebrightening in the afterglow of the short hard gamma ray burst (SHB) 130603B measured with the Hubble Space Telescope (HST) and an alleged late-time X-ray excess were interpreted as possible evidence of a neutron star ...

Magnetic activity and spectral behavior of RS CVn binary system (IM Pegasi) in the ultraviolet [PDF]
Scientific ReportsWe present observations from the International Ultraviolet Explorer (IUE) covering the period from 1981 to 1992 of the long-period single-lined RS Canum Venaticorum (RS CVn) binary star, IM Pegasi, to elucidate the spectral behavior and physical ...

Delayed Development of Cool Plasmas in X-Ray Flares from the Young Sun-like Star κ 1 Ceti
The Astrophysical Journal, 2023 The Neutron star Interior Composition Explorer (NICER) X-ray observatory observed two powerful X-ray flares equivalent to superflares from the nearby young solar-like star κ ^1 Ceti in 2019. NICER follows each flare from the onset through the early decay,

Analysis of Solar-like X-class Flare on Wolf 359 Observed Simultaneously with TESS and XMM-Newton
The Astrophysical Journal, 2023 We present an analysis of a flare on the Wolf 359 star based on simultaneous observations of Transiting Exoplanet Survey Satellite and XMM-Newton. A stellar flare with energy comparable to an X-class solar flare is analyzed on this star for the first ...

Evidence of Compton cooling during an X-ray flare supports a neutron star nature of the compact object in 4U1700-37 [PDF]
, 2010 Based on new Chandra X-ray telescope data, we present empirical evidence of plasma Compton cooling during a flare in the non pulsating massive X-ray binary 4U1700-37.

Outlook on Magnetohydrodynamical Turbulence and Its Astrophysical Implications
Fluids, 2023 Magnetohydrodynamical (MHD) turbulence is ubiquitous in magnetized astrophysical plasmas, and it radically changes a great variety of astrophysical processes.

The Giant X-Ray Flare of NGC 5905: Tidal Disruption of a Star, a Brown Dwarf, or a Planet? [PDF]
, 2002 We model the 1990 giant X-ray flare of the quiescent galaxy NGC 5905 as the tidal disruption of a star by a supermassive black hole. From the observed rapid decline of the luminosity, over a timescale of a few years, we argue that the flare was powered ...

Continuous heating of a giant X-ray flare on Algol [PDF]
, 1999 Giant flares can release large amounts of energy within a few days: X-ray emission alone can be up to ten percent of the star's bolometric luminosity.

A spatially resolved limb flare on Algol B observed with XMM-Newton [PDF]
, 2003 We report XMM-Newton observations of the eclipsing binary Algol A (B8V) and B (K2III). The XMM-Newton data cover the phase interval 0.35 - 0.58, i.e., specifically the time of optical secondary minimum, when the X-ray dark B-type star occults a major ...
