A helium plume racing ahead of TOI-3884 b and infrared flickers from WASP 121 reveal surprising details about distant worlds and their stars. New work also maps the cloudy weather of WASP-43 b and traces massive HD 74371’s return to a blue-supergiant phase, while search interest highlights Proxima Centauri, Alpha Centauri, and other stellar favorites.

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. The planet's signal was confirmed by its consisten...

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...

Image: TOI-159 b: A hot Jupiter with eccentric orbit around a young, pulsating star
Astronomers have confirmed TOI-159 b, a giant planet orbiting a young (about 150 million years old), fast-rotating, and pulsating Doradus star. This planet is the hottest known hot Jupiter with a significant orbital eccentricity, making it a rare find. The host star's rapid rotation and pulsations make such discoveries challenging, but the team used a combination of radial velocity, transit, and spectro-photometric data to confirm the planet and ...

Image: New companion candidate and spiral found in HD 142527
HD 142527 is a young star with a complex disk and a known low-mass companion. Using advanced imaging techniques with VLT/SPHERE, astronomers explored the inner region of the system, searching for hidden companions and features that shape the disk. They confirmed and updated properties of the known companion, HD 142527 B, and identified a new candidate companion about 14 au from the star, which could be a young planet, brown dwarf, or a disk featu...

Image: XO-3 b
Researchers observed the near-UV (NUV) transit of XO-3 b, a massive hot Jupiter with an eccentric orbit, using XMM-Newton and ground-based telescopes. The NUV transit was found to be 30-70% deeper than in the optical, suggesting a large NUV-absorbing atmosphere. Interestingly, the NUV transit occurred about 22 minutes later than expected from optical data, even though the optical transits showed no timing variations. The team explored possible...

Image: TRAPPIST-1 flares follow a single power law over four energy orders
TRAPPIST-1, an ultra-cool dwarf star, is known for frequent stellar flares that impact its planets' atmospheres and can interfere with observations. Researchers combined data from JWST and Kepler/K2 to analyze the flare-frequency distribution (FFD) across four orders of magnitude in energy. By converting all flare energies to the TESS bandpass and correcting for detection sensitivities, they found that the cumulative FFD follows a single power la...

Image: Brown dwarf, warm Jupiter, and hot super-Earth share coplanar orbits in TOI-201 system
Astronomers have discovered a remarkable planetary system around the young star TOI-201, featuring three very different companions: a hot super-Earth, a warm Jupiter, and a highly eccentric brown dwarf. Using long-term radial velocity and transit timing data, the team found that all three objects orbit in the same plane. The brown dwarf, with a mass about 16 times that of Jupiter and an 8-year orbit, is the longest-period transiting object ever c...

Image: Stellar models show HD 20794 preserves its chemical fingerprint over billions of years
HD 20794 is a nearby, metal-poor G-type star hosting a compact planetary system, including a super-Earth near the habitable zone. Scientists used detailed stellar evolution models to study its structure and chemical abundances. By comparing 252 models with observed properties like temperature, gravity, luminosity, and radius, they found the best fit for a star with 0.80 solar masses and an age of about 9 billion years. The models accurately re...
