A detection threshold in the amplitude spectra calculated from Kepler data obtained during K2 mission.
(Oxford University Press, 2015)We present our analysis of simulated data in order to derive a detection threshold which can be used in the pre-whitening process of amplitude spectra. In case of ground-based data of pulsating stars, this threshold is ... -
Modelling the rotation period distribution of M dwarfs in the Kepler field
(Springer Verlag, 2018)McQuillan et al. (Mon. Not. R. Astron. Soc.432:1203, 2013) presented 1570 periods P of M dwarf stars in the field of view of the Kepler telescope. It is expected that most of these reflect rotation periods, due to starspots. ... -
Spectroscopy of the variable K-dwarf UNSW-V-760: is it a pre-main-sequence pulsator?
(Oxford University Press, 2013)The star UNSW-V-760 is a known variable, showing both flares and two non-sinusoidal periodicities. Availability of high signal-to-noise spectra reported in this paper has enabled a revision of the spectral type of this ...
