AstroSat/LAXPC observation of Cygnus X-1 in the hard state
Ranjeev Misra, J S Yadav, Jai Verdhan Chauhan +10
We report the first analysis of data from AstroSat/LAXPC observations of Cygnus X-1 in January 2016. LAXPC spectra reveals that the source was in the canonical hard state, represen…
Standing on the shoulders of Dwarfs: the Kepler asteroseismic LEGACY sample II - radii, masses, and ages
Victor Silva Aguirre, Mikkel N. Lund, H. M. Antia +21
We use asteroseismic data from the Kepler satellite to determine fundamental stellar properties of the 66 main-sequence targets observed for at least one full year by the mission.…
Standing on the shoulders of Dwarfs: the asteroseismic LEGACY sample I - oscillation mode parameters
Mikkel N. Lund, Víctor Silva Aguirre, Guy R. Davies +17
The advent of space-based missions like has revolutionized the study of solar-type stars, particularly through the measurement and modeling of their resonant modes of osci…
Kepler Observations of the Asteroseismic Binary HD 176465
T. R. White, O. Benomar, V. Silva Aguirre +31
Binary star systems are important for understanding stellar structure and evolution, and are especially useful when oscillations can be detected and analysed with asteroseismology.…
AstroSat/LAXPC reveals the high energy variability of GRS 1915+105 in the chi class
J S Yadav, Ranjeev Misra, Jai Verdhan Chauhan +10
We present the first quick look analysis of data from nine {\it AstroSat}'s LAXPC observations of GRS 1915+105 during March 2016 when the source had the characteristics of being in…
SpaceInn hare-and-hounds exercise: Estimation of stellar properties using space-based asteroseismic data
D. R. Reese, W. J. Chaplin, G. R. Davies +15
Context: Detailed oscillation spectra comprising individual frequencies for numerous solar-type stars and red giants are or will become available. These data can lead to a precise…
