Low mass ratio contact binaries
We performed photometric, spectroscopic and orbital period investigations of ASASSN-V J015428.67+204247.2 (hereafter, J015428) for the first time. The light curves of VRI bands... -
Kepler main sequence star super-flare
We wrote and used an automated flare detection Python script to search for super-flares on main sequence stars of types A, F, G, K and M in Kepler's long-cadence data from Q0 to... -
Main sequence magnetic stars properties
We reconsidered the previous studies of properties of magnetic stars based on the latest data on average surface magnetic fields of 177 stars. New, corrected results have been... -
LAMOST stars radii, masses, luminosities
Based on the spectral observations of the LAMOST (DR2) survey, the radii, masses, and luminosities of 700480 stars were estimated. These stars belong to spectral types A, F, G,... -
Accurate masses and radii of normal stars
This article presents and discusses a critical compilation of accurate, fundamental determinations of stellar masses and radii. We have identified 95 detached binary systems... -
Eccentricity distribution of giant planets
Eccentric giant planets are predicted to have acquired their eccentricity through two major mechanisms: the Kozai-Lidov effect or planet-planet scattering, but it is normally... -
Late-type stars in the DFBS
We present a new value-added catalogue of late-type stars (LTS), M giants, M dwarfs as well as new C (carbon) stars of N and CH-types from the analysis of the Digitized First... -
RVs of GaiaDR2 comoving wide binary stars
The gravitational redshift induced by stellar surface gravity is notoriously difficult to measure for non-degenerate stars, since its amplitude is small in comparison with the... -
Stellar parameters study with SED fit algo
Accurately measuring stellar parameters is a key goal to increase our understanding of the observable Universe. However, current methods are limited by many factors, in... -
Study of UCD's flares from SSO survey
We present a study of photometric flares on 154 low-mass (<=0.2 M_{sun}_) objects observed by the SPECULOOS-South Observatory from 2018 June 1 to 2020 March 23. In this... -
TESS Triple-9 Catalog
The Transiting Exoplanet Survey Satellite (TESS) has detected thousands of exoplanet candidates since 2018, most of which have yet to be confirmed. A key step in the... -
Study of Kepler's FGKM stars
While stellar rotation periods P_rot_ may be measured from broad-band photometry, the photometric modulation becomes harder to detect for slower rotators, which could bias... -
KOI planets and KIC stars from Kepler DR25
In order to gain a better understanding of planet formation and evolution, it is important to examine the statistics of exoplanets in the Galactic context. By combining... -
Planetary systems study with GALAH surveys
Pioneering photometric, astrometric, and spectroscopic surveys is helping exoplanetary scientists better constrain the fundamental properties of stars within our galaxy and the... -
Flares in the Kepler short cadence data
We present the results of a search for stellar flares from stars neighbouring the target sources in the Kepler short cadence data. These flares have been discarded as... -
Giant stars in TESS continuous viewing zones
The NASA Transiting Exoplanet Survey Satellite (NASA-TESS) mission presents a treasure trove for understanding the stars it observes and the Milky Way, in which they reside. We... -
Confirming known planetary trends with Kepler
Statistical studies of exoplanets and the properties of their host stars have been critical to informing models of planet formation. Numerous trends have arisen in particular... -
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... -
Stars in the Earth transit zone
Transit observations have found the majority of exoplanets to date. Also spectroscopic observations of transits and eclipses are the most commonly used tool to characterize... -
Stellar and planetary parameters from TEPCAT
We present a publicly available library of model atmospheres with radiative-convective equilibrium pressure-temperature (P-T) profiles fully consistent with equilibrium chemical...
