Detecting Multi-Planetary Systems with Gravitational Microlensing and the Roman Space Telescope
It is plausible that most of the Stars in the Milky Way (MW) Galaxy, like the Sun, consist of planetary systems, instead of a single planet. Out of the estimately […]
A Search for Extraterrestrial Technosignatures in Archival FAST Survey Data Using a New Procedure
The aim of “search for extraterrestrial intelligence” (SETI) commensal surveys is to scan the sky to find possible technosignatures from the extraterrestrial intelligence (ETI).
Terrestrial And Neptune Mass Free-floating Planet Candidates From The MOA-II 9-year Galactic Bulge Survey
We report the discoveries of low-mass free-floating planet (FFP) candidates from the analysis of 2006-2014 MOA-II Galactic bulge survey data.
Free-floating or wide-orbit? Keck Adaptive-optics Observations Reveal No Host Stars Near Free-Floating Planet Candidates
Recent detections of extremely short-timescale microlensing events imply the existence of a large population of Earth- to Neptune-mass planets that appear to have no host stars.
Watching A Star Devour A Planet: The Ultimate Fate Of Earth?
By studying countless stars at various stages of their evolution, astronomers have been able to piece together an understanding of the life cycle of stars and how they interact with […]
Multiplicity Boost Of Transit Signal Classifiers: Validation of 69 New Exoplanets Using The Multiplicity Boost of ExoMiner
Most existing exoplanets are discovered using validation techniques rather than being confirmed by complementary observations.
Metal-Poor Stars Are More Life-Friendly
Stars that contain comparatively large amounts of heavy elements provide less favourable conditions for the emergence of complex life than metal-poor stars, as scientists from the Max Planck Institutes for […]
TOI-733 b – A Planet In The Small-planet Radius Valley Orbiting A Sun-like Star
We report the discovery of a hot (Teq ≈ 1055 K) planet in the small planet radius valley transiting the Sun-like star TOI-733, as part of the KESPRINT follow-up program […]
Digging Into The Interior Of Hot Cores With ALMA (DIHCA). III: The Chemical Link Between NH2CHO, HNCO, And H2CO
We have analyzed the NH2CHO, HNCO, H2CO, and CH3CN (13CH3CN) molecular lines at an angular resolution of ∼0.3″ obtained by the Atacama Large Millimeter/submillimeter Array (ALMA) Band 6 toward 30 […]
