V1298 Tau b showed helium absorption during all four observed transits across four years, but its active host star may affect the signal. The latest findings also point to silicate clouds on TOI-561 b, a warped dust ring around CQ Tau, and a giant planet candidate near Boyajian's star that may be surrounded by vast rings. New atmospheric models reveal why gas compositions can vary across hot giant planets.

Image: Subgiant star TOI-5882’s lithium excess hints at planet engulfment
TOI-5882 is a subgiant star that stands out for its unusually high lithium content. The star also hosts a massive brown dwarf companion, which can disturb the orbits of any inner planets. Theoretical models suggest that subgiant stars in a certain mass range can retain lithium signatures if they have recently swallowed a planet. To test this, researchers measured the lithium abundance in TOI-5882 using high-resolution spectra and compared it to a control group of similar subgiants. They found th...

Image: Gliese 3378b’s new mass and orbit place it near the cosmic shoreline
Gliese 3378 (GJ 3378) is a red dwarf star located just 7.7 parsecs from the Sun. It hosts a planet, Gliese 3378b, which was previously thought to be a super-Earth with a mass of about five Earth masses and an orbital period of nearly twenty-five days. New observations using several high-precision spectrographs, including HPF, NEID, CARMENES, and SPIRou, have led to a revised understanding of this planet’s properties. The updated analysis finds th...

Image: Bayesian analysis shows LTT 1445A b may lack a thick atmosphere
LTT 1445A b is a rocky planet orbiting a red dwarf star, and astronomers are using the James Webb Space Telescope to search for signs of an atmosphere. This study introduces a new method that uses climate models and Bayesian statistics to analyze eclipse spectra, which are measurements of the planet’s heat as it passes behind its star. The method fits the observed data with models that account for the planet’s temperature and possible atmospheric...

Image: JWST reveals no clear atmosphere features on rocky planet LTT 1445 A b
LTT 1445 A b is the closest known rocky planet orbiting a red dwarf star. Scientists used the James Webb Space Telescope (JWST) to observe the planet as it passed in front of its star, measuring how starlight filtered through its atmosphere at wavelengths between three and five micrometers. Two independent data analysis methods were used to ensure the results were reliable. The observations achieved very high precision, allowing researchers to lo...

Image: TRAPPIST-1 planets’ climates modeled with energy balance approach
TRAPPIST-1 is a system of planets orbiting a low-mass star, with several planets considered potentially habitable. This study uses a version of the HEXTOR energy balance model to explore the possible climate states of these planets, focusing on those that are similar to Earth and orbit in a way that keeps the same side facing their star. The model is first tested on rapidly rotating, Earth-like planets and shows expected patterns of climate stabi...

Image: HAT-P-70b’s atmosphere shows metal signatures and dynamic winds
HAT-P-70b is an ultra-hot Jupiter, a type of giant planet that orbits very close to its star and experiences extreme temperatures. The dayside of HAT-P-70b is so hot that many metals become ionized, while the nightside remains cool enough for some elements to condense. Using the MAROON-X high-resolution spectrograph, researchers studied the planet’s atmosphere and detected fourteen different metals, including iron, titanium, calcium, chromium, so...

Image: Temperate super-Earth found orbiting nearby red dwarf Ross 318
Ross 318 (Gliese 48) is a red dwarf star with strong magnetic activity and a rotation period of about fifty-one and a half days. Researchers analyzed over a decade of radial velocity data from CARMENES and HIRES, along with TESS space telescope observations, to search for planets around this star. They discovered a planet, Ross 318 b (Gliese 48 b), which has a minimum mass about six times that of Earth and orbits the star every thirty-nine days. ...

Image: V1094 Sco disk shows planet-driven and gravitationally formed rings
V1094 Sco is a large protoplanetary disk that displays several pairs of rings and gaps far from its central star. Using high-resolution images from the Atacama Large Millimeter/submillimeter Array and the Very Large Telescope, researchers studied the disk's structure in detail. The dust in the disk forms four narrow ring-gap pairs at large distances, while gas traced by carbon monoxide extends even farther and moves in a pattern called Keplerian ...

Image: Possible outer giant planet or brown dwarf found in 51 Pegasi system
51 Pegasi is a Sun-like star known for hosting the first confirmed planet outside our solar system. Recent research has analyzed over thirty years of data to search for another, more distant companion in this system. Scientists combined radial velocity measurements, astrometry, and high-contrast imaging to look for signs of a giant planet or brown dwarf far from the star. The data show a slight acceleration in the star's motion, which could be ca...

Image: Two planets orbiting orange dwarf TOI-4311 reveal dense super-Earth and sub-Neptune
TOI-4311 is an orange dwarf star located between the Galactic thick disk and Hercules stream. This star hosts two planets: an ultra-short-period super-Earth and a longer period sub-Neptune. The super-Earth completes an orbit in about one day and is very dense, while the sub-Neptune has a longer orbit of around fifteen days. These planets were first detected by the TESS space telescope, and their properties were refined using CHEOPS and HARPS obse...
