TESS Observations of Seven Newly Identified High-amplitude Scuti Stars
Chenglong Lv, Ali Esamdin, Amir Hasanzadeh +3
We report seven newly identified high-amplitude Scuti (HADS) stars. Among them, two stars (TIC 30977864 and TIC 387379145) exhibit pure radial pulsation without the excitation…
Spatio-temporal analysis of helioseismic quasi-biennial oscillations
Amir Hasanzadeh, Anne-Marie Broomhall, Dmitrii Kolotkov +1
Quasi-biennial oscillations (QBOs) are shorter-term periodic signals that occur alongside the dominant 11-year solar cycle. In this study, we examine the spatial and temporal evolu…
Effects of the photospheric cut-off on the p-mode frequency stability
Dmitrii Y. Kolotkov, Anne-Marie Broomhall, Amir Hasanzadeh
Sub-photospheric acoustic resonators allow for the formation of standing p-mode oscillations by reflecting acoustic waves with frequencies below the acoustic cut-off frequency. We…
TESS Cycle 2 observations of roAp stars with 2-min cadence data
D. L. Holdsworth, M. S. Cunha, M. Lares-Martiz +46
We present the results of a systematic search of the Transiting Exoplanet Survey Satellite (TESS) 2-min cadence data for new rapidly oscillating Ap (roAp) stars observed during the…
First results on RR Lyrae stars with the TESS space telescope: untangling the connections between mode content, colors and distances
László Molnár, Attila Bódi, András Pál +25
The TESS space telescope is collecting continuous, high-precision optical photometry of stars throughout the sky, including thousands of RR Lyrae stars. In this paper, we present r…
