The formation and evolution of ultra-short-period (USP) rocky planets is poorly understood. However, it is widely thought that these planets could not have formed at their...

Previous studies showed evidence of a dearth of close-in exoplanets around fast rotators, which can be explained by the combined action of intense tidal and magnetic...

Ultra-hot Jupiters are gas giant exoplanets strongly irradiated by their star, which sets intense molecular dissociation leading to atmospheric chemistry dominated by ions and...

This is a table that simply gives, for each object in Gaia eDR3, the identifier of its closest neighbour together with the distance of the pair.

NGC 2506 is a rich, intermediate-age (2.0Gyr), metal-poor ([Fe/H]~-0.2) open cluster. This work presents the results of 12,157 spectroscopic radial-velocity measurements of 2442...

Modeling observations of transiting exoplanets or close binary systems by comparing the observations with theoretical light curves requires precise knowledge of the distribution...

Using high-precision photometry, NASA's TESS space mission has discovered many intriguing transiting planet candidates. These discoveries require ground-based follow-up...

The study of blue straggler stars (BSS) provides insights into the mechanisms of stellar mass exchange during binary stellar evolution and the complex gravitational interactions...

Complete, accurate, and precise catalogues of exoplanet host star (EHS) properties are essential to derive high-quality exoplanet parameters, and, thus, to study individual...

In this paper we present the latest results of our ongoing multiplicity survey of (Community) TESS Objects of Interest, using astrometry and photometry from the latest data...

We present the discovery of TOI 762 A b and TIC 46432937 b, two giant planets transiting M-dwarf stars. Transits of both systems were first detected from observations by the...

The origin and evolution of the sub-Neptune population is a highly debated topic in the exoplanet community. With the advent of JWST, atmospheric studies can now put...

With around 200 detections of exoplanets around giant stars to date, our knowledge of the population of exoplanets orbiting evolved hosts more massive than the Sun remains...

The archive of digitized plates obtained on Schmidt telescope (large camera) at the Fesenkov Astrophysical Institute (FAI), Almaty, Kazakhstan. They represent the results of...

The archive of digitized plates obtained on Wide aperture Maksutov meniscus telescope with main mirror 50 cm at the Fesenkov Astrophysical Institute (FAI), Almaty, Kazakhstan....

We search for low-mass companions of M dwarfs and characterize their multiplicity fraction with the purpose of helping in the selection of the most appropriate targets for the...

The Hubble Space Telescope Fine Guidance Sensors data on 23 stars in the intermediate-age cluster M35 having B-V<0.5 (~F7V) are analyzed to test whether binary periods,...

We present the results of a deep-imaging search for wide companions to low-mass stars and brown dwarfs using NSFCam on the Infrared Telescope Facility. We searched a sample of...

A comparative study of the population of the galactic binary stars is performed for two modes of star formation: star formation at a constant rate over 10^+10^yrs, and a burst...

We report the discovery of a super-Earth orbiting the star GJ 536 based on the analysis of the radial-velocity time series from the HARPS and HARPS-N spectrographs. GJ 536 b is...
