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…

Amplitude modulation in Sct stars: statistics from an ensemble study of Kepler targets

Dominic M. Bowman, Donald W. Kurtz, Michel Breger +2

We present the results of a search for amplitude modulation of pulsation mode frequencies in 983 Sct stars, which have effective temperatures between 6400 $\leq T_{\rm eff} \le…

Nonradial and radial period changes in the Delta Scuti star 4 CVn I. 700+ nights of photometry

Michel Breger

The nature of period and amplitude changes in nonradial pulsators is presently unknown. It is therefore important to examine the correlations between these changes in stars with a…

Discovery of binarity, spectroscopic frequency analysis, and mode identification of the delta Sct star 4CVn

V. S. Schmid, N. Themeßl, M. Breger +12

More than 40 years of ground-based photometric observations of the delta Sct star 4CVn revealed 18 independent oscillation frequencies, including radial as well as non-radial p-mod…

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…

Pulsation analysis and its impact on primary transit modeling in WASP-33

C. von Essen, S. Czesla, U. Wolter +6

To date, WASP-33 is the only delta Scuti star known to be orbited by a hot Jupiter. The pronounced stellar pulsations, showing periods comparable to the primary transit duration, i…
