We present a second-order analytical expansion of null equatorial geodesics in the Kerr metric. The equations developed are applied to the study of light...

We release a new grid of stellar limb-darkening coefficients (LDCs, using the quadratic, power-2 and claret-4 laws) and intensity profiles for the Kepler, U, B...

Using photometry collected with the Zwicky Transient Facility, we are conducting an ongoing survey for binary systems with short orbital periods ( ${P}_{{\rm{b}...

A new uvby and H-beta monitoring program of low mass eclipsing binaries is currently being carried out in the framework of a 5-yr observational program which...

We report the discovery of two new pulsating extremely low-mass pre-white dwarf (pre-ELMV) candidates in the Transiting Exoplanet Survey Satellite (TESS)...

APOGEE spectra offer ≲1 km s -1 precision in the measurement of stellar radial velocities. This holds even when multiple stars are captured in the same spectrum...

We present a photometric survey aimed at the identification of variable stars in the galactic globular cluster ω Cen. Our photometric catalogue is based on ~...

We present a detailed analysis of an eclipsing double-lined binary FX UMa based on TESS photometry and newly acquired spectroscopic observations. The radial...

We give an overview of a project aiming to identify new eclipsing post common envelope binaries from the Sloan Digital Sky Survey. This work focuses on the...
