CRIRES high-resolution infrared spectroscopy of the long-period Cepheid l Car
N. Nardetto, E. Poretti, A. Gallenne +17
The dynamical structure of the atmosphere of Cepheids has been well studied in the optical. Several authors have found very interesting spectral features in the J band, but little…
All-sky RR Lyrae Stars in the Gaia Data
Lorenzo Rimoldini, Laurent Eyer, Nami Mowlavi +22
The second Gaia data release is expected to contain data products from about 22 months of observation. Based on these data, we aim to provide an advance publication of a full-sky G…
Cyclic variations in the periods of RR Lyr stars
Ennio Poretti, Jean-Francois Le Borgne, Alain Klotz +2
We report here on two types of cyclic variations that can be observed in the periods of RR Lyr stars, i.e., the Blazhko and the light-time effects. The former has been investigated…
