Double-Mode RR Lyrae Stars Observed by K2: Analysis of High-Precision Kepler Photometry
James M. Nemec, Amanda F. Linnell Nemec, Pawel Moskalik +4
The results of a Fourier analysis of high-precision Kepler photometry of 75 double-mode RR~Lyrae (RRd) stars observed during NASA's K2 Mission (2014-18) are presented. Seventy-two…
V473 Lyr, a modulated, period-doubled Cepheid, and U TrA, a double-mode Cepheid observed by MOST
L. Molnár, A. Derekas, R. Szabó +36
Space-based photometric measurements first revealed low-amplitude irregularities in the pulsations of Cepheid stars, but their origins and how commonly they occur remain uncertain.…
Gaia Data Release 1. Summary of the astrometric, photometric, and survey properties
Gaia Collaboration, A. G. A. Brown, A. Vallenari +5
At about 1000 days after the launch of Gaia we present the first Gaia data release, Gaia DR1, consisting of astrometry and photometry for over 1 billion sources brighter than magni…
The Gaia mission
Gaia Collaboration
Gaia is a cornerstone mission in the science programme of the European Space Agency (ESA). The spacecraft construction was approved in 2006, following a study in which the original…
Kepler photometry of RRc stars: peculiar double-mode pulsations and period doubling
P. Moskalik, R. Smolec, K. Kolenberg +11
We present the analysis of four first overtone RR Lyrae stars observed with the Kepler space telescope, based on data obtained over nearly 2.5yr. All four stars are found to be mul…
An In-Depth Spectroscopic Analysis of RR Lyr Variations over the Pulsation Cycle
L. Fossati, K. Kolenberg, D. V. Shulyak +5
The stellar parameters of RR Lyrae stars vary considerably over a pulsation cycle, and their determination is crucial for stellar modelling. We present a detailed spectroscopic ana…
