A distant planet is shedding helium ahead of its transit, while another world hides a cloudy nightside beneath a clearer dayside. New observations also reveal stellar vibrations in infrared light, trace a massive star’s journey beyond its red-supergiant phase, and expose the magnetic activity of a young planetary system.

Image: PALEOS toolkit models exoplanet interiors with phase-aware equations of state
Understanding the interior structure of rocky and water-rich exoplanets requires accurate equations of state (EoS) that describe how materials behave under different pressures and temperatures. The new PALEOS toolkit brings together EoS for iron, magnesium silicate, and water into a unified, phase-aware framework that covers 17 different material phases. This allows scientists to model density, energy, entropy, heat capacity, and other properties across a planet's interior, from surface to core....

Image: GJ 1132 b receives intense XUV radiation, likely losing its atmosphere
GJ 1132 b is an Earth-sized planet orbiting a small red dwarf star every 1.6 days. Scientists studied how much high-energy XUV radiation the planet has received over its lifetime, which is important for understanding whether it can keep an atmosphere. By analyzing the star's activity and flare history, they found that GJ 1132 b has likely received at least 50 times more XUV radiation than Earth does today. The study compared different models f...

TOI-1710 b: a super-Neptune on a retrograde, strongly misaligned orbit challenges planet migration theories

Image: TOI-1710 b: a super-Neptune on a retrograde, strongly misaligned orbit challenges planet migration theories
TOI-1710 b is a super-Neptune planet orbiting a cool star, but unlike most planets, its orbit is strongly misaligned and retrograde, meaning it moves in the opposite direction to the star's rotation. This was determined using high-precision radial velocity measurements during a transit, which revealed a large angle between the planet's orbital plane and the star's spin axis. The planet's orbit is wide enough that tidal forces have not altered ...

Two exoplanets were confirmed orbiting a nearby red dwarf star TOI-1752, making it a valuable system for studying planetary diversity. The inner planet, TOI-1752 b, orbits very close to the star and is likely a lava world, with surface temperatures high enough to melt rock. The outer planet, TOI-1752 c, is a sub-Neptune-size planet that orbits within the optimistic habitable zone, where conditions could allow for liquid water. Researchers comb...

The T16 project analyzed light curves from the TESS space telescope's first cycle, focusing on stars as faint as 16th magnitude. By using advanced data processing and machine learning, the team searched for transiting exoplanets in over 83 million light curves. This large-scale search resulted in the identification of 11,554 planet candidates, including 10,091 that are new discoveries. The candidates have orbital periods between half a day and 27...

Image: TOI-5624 hosts four transiting sub-Neptunes and a fifth outer planet revealed by timing variations
TOI-5624 is a Sun-like star about 100 parsecs away, now known to host a remarkable planetary system. Observations from TESS and CHEOPS revealed four transiting sub-Neptune planets with orbital periods of about 3.4, 7.9, 13.7, and 21.5 days. Their radii range from about 2.3 to 3.6 times that of Earth, and their masses are between 4.8 and 9.4 Earth masses. The outermost planet, TOI-5624 e, shows significant variations in its transit timing, which l...

Image: High-resolution spectroscopy reveals signs of CO2 in the cloudy atmosphere of GJ 1214 b
GJ 1214 b is a sub-Neptune exoplanet known for its cloudy atmosphere, which has made it difficult to detect specific molecules. Using high-resolution K-band spectroscopy, scientists observed eight transits of the planet and searched for atmospheric signatures. While water vapor, methane, hydrogen sulfide, ammonia, and carbon monoxide were not detected, the data show a possible signal from carbon dioxide (CO2) at a confidence level of 3.4 sigma. ...

Image: JWST images reveal CO2 and high metallicity in super-Jupiter 29 Cyg b, hinting at disk formation
29 Cyg b is a massive companion to the star 29 Cygni, with a mass near the boundary between giant planets and brown dwarfs. Using the James Webb Space Telescope, astronomers directly imaged the planet and detected strong absorption from carbon monoxide and carbon dioxide in its atmosphere. The strength of the CO2 feature compared to CO indicates that 29 Cyg b is enriched in heavy elements, or metals, relative to its host star. This enhanced me...

Image: Hidden companion may explain GJ 436 b
GJ 436 b is a hot Neptune with a polar and eccentric orbit, making it a rare example among planets in the so-called sub-Jovian desert. Scientists analyzed 20 years of radial velocity and astrometric data to search for a distant, unseen companion that could explain the planet's unusual orbit. Their results set strong limits on the possible mass and distance of such a companion, ruling out massive objects close to the star but allowing for a sub-Jo...

Image: White dwarf WD J000801.25-350450 and its companions form a possible quadruple system
WD J000801.25-350450 is a white dwarf star with two widely separated, co-moving companions. New spectroscopic observations confirm that the white dwarf is hydrogen-rich, with a temperature of about 6200 Kelvin and a mass similar to the average white dwarf. The inner companion is an M8-type red dwarf, while the outer companion appears to be a binary system made up of M6 and M9-type stars. This configuration suggests that the system may actually...
