Non-radial modes in classical Cepheids. What to look for in spectroscopy?
H. Netzel, K. Kolenberg
Recent photometric observations of first-overtone classical Cepheids and RR Lyrae stars have led to the discovery of additional frequencies showing a characteristic period ratio of…
K2 Observations of Galactic RRd Stars
Paweł Moskalik, James M. Nemec, László Molnár +3
We have analysed high-precision photometry of 77 double-mode RR Lyrae (RRd) stars observed by NASA's Kepler-K2 mission during Campaigns 1-18. Among those stars, we have identified…
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…
Stars at High Spatial Resolution
Kenneth G. Carpenter, Gerard van Belle, Alexander Brown +19
We summarize some of the compelling new scientific opportunities for understanding stars and stellar systems that can be enabled by sub-milliarcsec (sub-mas) angular resolution, UV…
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…
The evolutionary nature of RV Tauri stars in the SMC and LMC
Rajeev Manick, Hans Van Winckel, Devika Kamath +2
Based on their stellar parameters and the presence of a mid-IR excess due to circumstellar dust, RV Tauri stars have been classified as post-AGB stars. Our recent studies, however,…
