Rotational and pulsational variability in the TESS light curve of HD27463
V. Khalack, C. Lovekin, D. M. Bowman +8
The new photometric data on pulsating Ap star HD~27463 obtained recently with the Transiting Exoplanet Survey Satellite (\textit{TESS}) are analysed to search for variability. Our…
Nonradial and radial period changes of the Delta Scuti star 4 CVn II. Systematic behavior over 40 years
M. Breger, M. H. Montgomery, P. Lenz +1
Pulsators on and near the main sequence show period and amplitude changes that are too large to be the product of stellar evolution. The multiperiodic Delta Scuti stars are well su…
Refining the asteroseismic model for the young delta Scuti star HD 144277 using HARPS spectroscopy
Konstanze Zwintz, Tatiana Ryabchikova, Patrick Lenz +8
HD 144277 was previously discovered by MOST space photometry to be a young and hot delta Scuti star showing regular groups of pulsation frequencies. The first asteroseismic models…
Detection of high-degree prograde sectoral mode sequences in the A-star KIC 8054146?
M. Breger, P. Lenz, A. A. Pamyatnykh
This paper examines the 46 frequencies found in the Delta Sct star KIC 8054146 involving a frequency spacing of exactly 2.814 c/d (32.57 microHz), which is also a dominant low-freq…
Relationship between low and high frequencies in Delta Scuti stars: Photometric Kepler and spectroscopic analyses of the rapid rotator KIC 8054146
M. Breger, L. Fossati, L. Balona +9
Two years of Kepler data of KIC 8054146 (delta Sct/gamma Dor hybrid) revealed 349 statistically significant frequencies between 0.54 and 191.36 c/d (6.3 microHz to 2.21 mHz). The 1…
Asteroseismology of stars on the upper main sequence
P. Lenz
I review the properties of pulsators located on the upper main sequence in the HR diagram and discuss asteroseismic inferences on the internal structure of stars of spectral type A…
