M-dwarf stars provide us with an ideal opportunity to study nearby small planets. The HUnting for M Dwarf Rocky planets Using MAROON-X (HUMDRUM) survey uses the MAROON-X...

The Decadal Survey on Astronomy and Astrophysics 2020 has recommended that NASA realize a large IR/optical/UV space telescope optimized for high-contrast imaging and...

The Neptunian desert and savanna have been recently found to be separated by a ridge, an overdensity of planets in the ~3-5 days period range. These features are thought to be...

Accurate atmospheric parameters and chemical composition of planet hosts play a major role in characterizing exoplanets and understanding their formation and evolution. Our...

The inner disk of the young star PDS 70 may be a site of rocky planet formation, with two giant planets detected further out. Recently, JWST/MIRI MRS observations have revealed...

Recent observations of giant planets have revealed unexpected bulk densities. Hot Jupiters, in particular, appear larger than expected for their masses compared to planetary...

SWEET-Cat (Stars With ExoplanETs Catalogue) was originally introduced in 2013, and since then, the number of confirmed exoplanets has increased significantly. A crucial step for...

Measurements of the obliquities in exoplanet systems have revealed some remarkable architectures, some of which are very different from the Solar System. Nearly 200 obliquity...

K2-24 is a planetary system composed of two transiting low-density Neptunians locked in an almost perfect 2:1 resonance and showing large TTVs, i.e., an excellent laboratory to...

We present a search for close, unresolved companions in a subset of spatially resolved Gaia wide binaries containing main-sequence stars within 200 pc of the Sun, utilizing the...

We present the discovery of 17 double white dwarf (WD) binaries from our ongoing search for extremely low mass (ELM) <0.3M_{sun} WDs, objects that form from binary evolution....

Results of the speckle-interferometry observations at the 4.1m Southern Astrophysical Research Telescope obtained during 2023 are presented: 1913 measurements of 1533 resolved...

The list of 409 probable cluster members down to G=15mag (m>=0.5M_{sun}_) is compiled for the two degree radius of the Pleiades, based on astrometric data from Gaia DR3 and...

Young planetary systems represent an opportunity to investigate the early stages of (exo)planetary formation because the gravitational interactions have not yet significantly...

The long-term Global Architecture of Planetary Systems (GAPS) programme has been characterising a sample of young systems with transiting planets via spectroscopic and...

The nature of the close-in rocky planet 55 Cnc e is puzzling despite having been observed extensively. Its optical and infrared occultation depths show temporal variability, in...

ESPRESSO guaranteed time observations (GTO) at the 8.2m-VLT telescope aimed at finding Earth-like exoplanets in the habitable zone of nearby stars. Barnard's star is a primary...

This catalog is abstracted from the Card Catalog maintained at the University of Florida containing information on all published, and to the extent available, unpublished work...

The intensity of Jupiter's auroral radio emission quickly gave rise to the question whether a comparable coherent emission from the magnetosphere of an exoplanet could be...

The catalog contains 206 spectroscopic binary systems with at least one late-type component that shows Ca II H and K emission in its spectrum. These systems include the...
