TIC 441725813 spectrum and prewhitened frequencies
The Transiting Exoplanet Survey Satellite (TESS) performs high-precision photometry over almost the whole sky primarily in search of exoplanet transits. It also provides... -
Variable stars study with TESS
From sector 1-44 TESS observations, 19 new rapidly oscillating Ap (roAp) stars, 103 ostensibly non-peculiar stars with roAp-like frequencies, and 617 {delta} Scuti stars with... -
Asteroseismic study of TESS mission's DSCTs
We investigate the relationship between the asteroseismic indices and the physical quantities of 438 {delta} Scuti (DSCT) stars observed by the Transiting Exoplanet Survey... -
Asteroseismic modelling of solar-type stars
Detailed understanding of stellar physics is essential towards a robust determination of stellar properties (e.g. radius, mass, and age). Among the vital input physics used in... -
Mode identification in 3 pulsating hot subdwarfs
We report on the detection of pulsations of three pulsating subdwarf B stars observed by the Transiting Exoplanet Survey Satellite (TESS) satellite and our results of mode... -
Luminosities of 34 slowly pulsating B stars
We provide three statistical model prescriptions for the bolometric corrections appropriate for B-type stars as a function of (i) T_eff_, (ii) T_eff_ and logg, and (iii) T_eff_,... -
Pulsation properties of {lambda}bootis stars I
We analyse TESS light curves for 70 southern {lambda} Boo stars to identify binaries and to determine which of them pulsate as {delta} Scuti stars. We find two heartbeat stars... -
Asteroseismology of luminous red giants with Kepler
While long-period variables (LPVs) have been extensively investigated, especially with MACHO and OGLE data for the Magellanic Clouds, there still exist open questions in their... -
{delta} Scuti and {gamma} Doradus stars in TESS
We present the first asteroseismic results for {delta} Scuti and {gamma} Doradus stars observed in Sectors 1 and 2 of the TESS mission. We utilize the 2-min cadence TESS data... -
APOKASC Evolutionary state of red-giant stars
The internal working of low-mass stars is of great significance to both the study of stellar structure and the history of the Milky Way. Asteroseismology has the power to... -
Masses and radii of Kepler and CoRoT targets
Recently, by analysing the oscillation frequencies of 90 stars, Yildiz, Celik Orhan & Kayhan have shown that the reference frequencies ({nu}min0, {nu}min1, and {nu}min2)... -
Bayesian hierarchical inferred inclinations
The stellar inclination angle - the angle between the rotation axis of a star and our line of sight - provides valuable information in many different areas, from the... -
Red giant solar-like oscillations in Kepler data
The recently published Kepler mission Data Release 25 (DR25) reported on ~197000 targets observed during the mission. Despite this, no wide search for red giants showing... -
Gaia-derived luminosities of Kepler A/F stars
We study the fraction of stars in and around the {delta} Scuti instability strip that are pulsating, using Gaia DR2 parallaxes to derive precise luminosities. We classify a... -
14983 Kepler red giants
Deep learning in the form of 1D convolutional neural networks have previously been shown to be capable of efficiently classifying the evolutionary state of oscillating red... -
Deep learning classification in asteroseismology
In the power spectra of oscillating red giants, there are visually distinct features defining stars ascending the red giant branch from those that have commenced helium core... -
Red-giant stars classification
Determining the ages of red-giant stars is a key problem in stellar astrophysics. One of the difficulties in this determination is to know the evolutionary state of the... -
Anomalous RRd stars in Magellanic Clouds
We report the discovery of a new subclass of double-mode RR Lyrae stars in the Large and Small Magellanic Clouds. The sample of 22 pulsating stars has been extracted from the... -
Solar-like oscillators using TESS 2min cadence LCs
Based on all 2 minute cadence TESS light curves from Sector 1 to 60, we provide a catalog of 8651 solar-like oscillators, including frequency at maximum power ({nu}max, with its... -
Pulsating components in EBs from TESS
Based on 2 minute cadence TESS data from sectors 1-50, we report the results of the systematic extraction of {delta} Scuti-type pulsations in the 6431 eclipsing binaries with...
