This study aims to analyze Phobos' photometric properties using Mars Express mission observations to support the Martian Moons exploration mission (MMX) devoted to the...

We utilize the robust membership determination algorithm, ML-MOC, on the precise astrometric and deep photometric data from Gaia Early Data Release 3 within a region of radius 5...

Understanding when and how circumstellar disks disperse is crucial to constrain planet formation and migration. Thermal winds powered by high-energy stellar photons have long...

We developed a tool that measures equivalent widths of various lines in low-resolution optical spectra, and it was applied to stellar spectra obtained as part of SDSS-V and...

Extragalactic surveys provide significant statistical data for the conditions. These quantities are derived using manual or automatic methods for disturbances, star-forming...

The orientation between a star's spin axis and a planet's orbital plane provides valuable information about the system's formation and dynamical history. For non-transiting...

Gaia18cjb is one of the Gaia-alerted eruptive young star candidates which has been experiencing a slow and strong brightening during the last 13 years, similar to some FU...

T Pyx is one of the most enigmatic recurrent novae, and it has been proposed as a potential Galactic type-Ia supernova progenitor. Using spatially resolved data obtained with...

Dynamo models of stellar magnetic fields for partly and fully convective stars are guided by observational constraints. Zeeman-Doppler imaging has revealed a variety of magnetic...

High mass-loss rates of red supergiants (RSGs) drastically affect their evolution and final fate, yet their mass-loss mechanism remains poorly understood. Various empirical...

An intriguing pattern among exoplanets is the lack of detected planets between approximately 1.5R{Earth} and 2.0R{Earth}. One proposed explanation for this "radius gap" is the...

Young, low-mass brown dwarfs orbiting early-type stars, with low mass ratios (q<~0.01), appear to be intrinsically rare and present a formation dilemma: could a handful of...

We present 1-5{mu}m spectroscopy of the coldest known brown dwarf, WISEJ085510.83-071442.5 (WISE0855), performed with the Near-Infrared Spectrograph (NIRSpec) on board the James...

The MIRI instrument on board JWST is now offering high-contrast imaging capacity at mid-IR wavelengths, thereby opening a completely new field of investigation for...

Are WO-type Wolf-Rayet (WR) stars in the final stage of massive star evolution before core-collapse? Although WC- and WO-type WRs have very similar spectra, WOs show a much...

We investigate the incidence and properties of ionised gas outflows in a sample of 52 galaxies with stellar masses between 10^7^M_{sun} and 10^9^M{sun} observed with ultra-deep...

The statistical distribution and evolution of key properties of active galactic nuclei (AGN), such as their accretion rate, mass, or spin, remain an open debate in astrophysics....

Near-infrared bandpasses on spaceborne observatories diverge from their ground-based counterparts as they are free of atmospheric telluric absorption. Available transformations...

V1298 Tau is a young pre-main-sequence star hosting four known exoplanets that are prime targets for transmission spectroscopy with current-generation instruments. This work...

We present an updated catalog of 46753 radial velocity (RV) standard stars selected from the APOGEE DR17. These stars cover the Northern and Southern Hemispheres almost evenly,...
