An Earth-Mass Planet and a Brown Dwarf in Orbit Around a White Dwarf
Terrestrial planets born beyond 1-3 AU have been theorized to avoid being engulfed during the red-giant phases of their host stars.
The GAPS Programme at TNG. LXI. Atmospheric Parameters and Elemental Abundances of TESS Young Exoplanet Host Stars
The study of exoplanets at different evolutionary stages can shed light on their formation, migration, and evolution. The determination of exoplanet properties depends on the properties of their host stars. […]
ODUSSEAS: Upgraded Version With New Reference Scale and Parameter Determinations for 82 Planet-host M Dwarf Stars in SWEET-Cat
Aims: Obtaining accurate derivations of stellar atmospheric parameters is crucial in the fields of stellar and exoplanet characterization. We present the upgraded version of our computational tool ODUSSEAS with a […]
In Six New Rogue Worlds, Webb Telescope Finds More Star Birth Clues
The James Webb Space Telescope has spotted six likely rogue worlds—objects with planetlike masses but untethered from any star’s gravity—including the lightest ever identified with a dusty disk around it.
Earths Within Reach: Evaluation of Strategies for Mitigating Solar Variability Using 3.5 years Of NEID Sun-as-a-Star Observations
We present the results of Sun-as-a-star observations by the NEID Solar Telescope at WIYN Observatory, spanning January 1, 2021 through June 30, 2024. We identify 117,060 observations which are unlikely […]
Efficiently Searching for Close-in Companions Around Young M Dwarfs Using a Multi-year PSF Library
We present Super-RDI, a unique framework for the application of reference star differential imaging (RDI) to Keck/NIRC2 high-contrast imaging observations with the vortex coronagraph.
The JWST/NIRISS Deep Spectroscopic Survey for Young Brown Dwarfs and Free-Floating Planets
The discovery and characterization of free-floating planetary-mass objects (FFPMOs) is fundamental to our understanding of star and planet formation. Here we report results from an extremely deep spectroscopic survey of […]
Insect Astronomy: How Dung Beetles and the Milky Way Are Helping To Improve Navigation Systems
An insect species that evolved 130 million years ago is the inspiration for a new research study to improve navigation systems in drones, robots, and orbiting satellites.
Arecibo Wow! I: An Astrophysical Explanation for the Wow! Signal
The Ohio State University Big Ear radio telescope detected in 1977 the Wow! Signal, one of the most famous and intriguing signals of extraterrestrial origin. Arecibo Wow! is a new […]
