A Radial Velocity Search for Binary RR Lyrae Variables
Thomas G. Barnes, Elisabeth Guggenberger, Katrien Kolenberg
We report 272 radial velocities for 19 RR Lyrae variables. For most of the stars we have radial velocities for the complete pulsation cycle. These data are used to determine robust…
On the interpretation of the long-term cyclic period variations in RR Lyrae stars
M. Skarka, J. Liška, Á. Sódor +4
Many RR Lyrae stars show long-term variations of their pulsation period, some of them in a cyclic way. Such behaviour can be attributed to the light-travel time effect (LTTE) cause…
A cautionary tale of interpreting O-C diagrams: period instability in a classical RR Lyr Star Z CVn mimicking as a distant companion
M. Skarka, J. Liška, R. Dřevěný +4
We present a comprehensive study of Z CVn, an RR Lyrae star that shows long-term cyclic variations of its pulsation period. A possible explanation suggested from the shape of the O…
Mitigating the mass dependence in the scaling relation of red-giant stars
Elisabeth Guggenberger, Saskia Hekker, George C. Angelou +2
The masses and radii of solar-like oscillators can be estimated through the asteroseismic scaling relations. These relations provide a direct link between observables, i.e. effecti…
Stellar Parameters in an Instant with Machine Learning: Application to Kepler LEGACY Targets
Earl P. Bellinger, George C. Angelou, Saskia Hekker +3
With the advent of dedicated photometric space missions, the ability to rapidly process huge catalogues of stars has become paramount. Bellinger and Angelou et al. (2016) recently…
Fundamental Parameters of Main-Sequence Stars in an Instant with Machine Learning
Earl P. Bellinger, George C. Angelou, Saskia Hekker +3
Owing to the remarkable photometric precision of space observatories like Kepler, stellar and planetary systems beyond our own are now being characterized en masse for the first ti…
