The VELOCE modulation zoo II. Humps and splitting patterns in spectral lines of classical Cepheids
H. Netzel, R. I. Anderson, G. Viviani
Line splitting in spectral lines is observed in various types of stars due to phenomena such as shocks, spectroscopic binaries, magnetic fields, spots, and non-radial modes. In pul…
Matching seismic masses for RR Lyrae-type and oscillating red horizontal-branch stars in M4
László Molnár, Henryka Netzel, Madeline Howell +2
Globular clusters offer a powerful way to test the properties of stellar populations and the late stages of low-mass stellar evolution. In this paper we study oscillating giant sta…
VELOcities of CEpheids (VELOCE) I. High-precision radial velocities of Cepheids
Richard I. Anderson, Giordano Viviani, Shreeya S. Shetye +27
This first VELOCE data release comprises 18,225 high-precision RV measurements of 258 bona fide classical Cepheids on both hemispheres collected mainly between 2010 and 2022, along…
On the incidence rate of RR Lyrae stars with non-radial modes
H. Netzel, V. Varga, R. Szabo +2
Over the recent years, additional low-amplitude non-radial modes were detected in many of the first-overtone RR Lyrae stars. These non-radial modes form a characteristic period rat…
The VELOCE Modulation Zoo I. Spectroscopic detection of non-radial modes in the first-overtone Cepheids BG Crucis, QZ Normae, V0391 Normae, and V0411 Lacertae
H. Netzel, R. I. Anderson, G. Viviani
The photometric observations from the recent decade revolutionized our view on classical pulsators. Low-amplitude signals have been detected photometrically in addition to the domi…
Variable stars in galactic globular Clusters I. The population of RR Lyrae stars
Mauricio Cruz Reyes, Richard I. Anderson, Lucas Johansson +2
We present a comprehensive catalog of 2824 RR Lyrae stars (RRLs) residing in 115 Galactic globular clusters (GCs). Our catalog includes 1594 fundamental-mode (RRab), 824 first-over…
