Rotation and pulsation in Ap stars: first light results from TESS sectors 1 and 2
M. S. Cunha, V. Antoci, D. L. Holdsworth +36
We present the first results from the Transiting Exoplanet Survey Satellite (TESS) on the rotational and pulsational variability of magnetic chemically peculiar A-type stars. We an…
Direct detection of a magnetic field in the photosphere of the single M giant EK Boo: How common is magnetic activity among M giants?
R. Konstantinova-Antova, M. Auriere, C. Charbonnel +6
We study the fast rotating M5 giant EK Boo by means of spectropolarimetry to obtain direct and simultaneous measurements of both the magnetic field and activity indicators, in orde…
Abundance analysis of Am binaries and search for tidally driven abundance anomalies - III. HD116657, HD138213, HD155375, HD159560, HD196544 and HD204188
I. Stateva, I. Kh. Iliev, J. Budaj
We continue here the systematic abundance analysis of a sample of Am binaries in order to search for possible abundance anomalies driven by tidal interaction in these binary system…
TESS Cycle 1 observations of roAp stars with 2-min cadence data
D. L. Holdsworth, M. S. Cunha, D. W. Kurtz +41
We present the results of a systematic search for new rapidly oscillating Ap (roAp) stars using the 2-min cadence data collected by the Transiting Exoplanet Survey Satellite (TESS)…
Seismic investigation of the γ Dor star KIC 6462033: The first results of Kepler and ground-based follow up observations
C. Ulusoy, B. UlaÅ, M. Damasso +5
We present the first preliminary results on the analysis of ground-based time series of the γ Dor star KIC 6462033 (TYC 3144-646-1, V = 10.83, P = 0.69686 d) as well as Kepler pho…
High-resolution optical spectroscopy of Nova V392 Per
K. A. Stoyanov, T. Tomov, I. Stateva +1
Here we analyze high-resolution spectra of the Nova V392 Per obtained during the 2018 outburst. The H and H emission lines show a triple-peak structure with radial velociti…
