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.

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 days, and 411 are single-transit events where the...

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...

Modeling shows Gliese 486 b's water content depends on its early hydrogen-rich atmosphere

Image: Modeling shows Gliese 486 b
Gliese 486 b is a planet orbiting close to a red dwarf star, where intense radiation likely caused much of its original atmosphere to escape. Scientists used computer models to study how the planet's current water content could be explained by different combinations of an early hydrogen-rich atmosphere and water inventory. They found that even a small amount of hydrogen in the early atmosphere could have protected water from escaping, reducing th...

Image: Hydrogen sulfide detected in the inner disk of HD 163296 reveals sulfur ice sublimation
HD 163296 is a young star surrounded by a disk of gas and dust where planets are forming. Using the ALMA telescope, scientists detected compact emission of hydrogen sulfide (H2S) and sulfur oxides in the innermost part of the disk. The emission comes from a region just 3–5 astronomical units from the star, where temperatures are high enough for sulfur-bearing ices to turn into gas. The observations show that H2S is a major sulfur-containing mo...

HD 161098 is a Sun-like star located about 30 parsecs away. Using advanced instruments and long-term radial velocity monitoring, scientists have detected two signals that may indicate the presence of planets. The first candidate, HD 161098 b, has a minimum mass of about 3.6 times that of Earth and orbits the star every 72.6 days. The second, HD 161098 c, is more massive, with a minimum mass of about 7.8 Earth masses and an orbital period of 682.5...

Image: HD 25295 b confirmed as a hot sub-Neptune and prime target for future atmospheric studies
HD 25295 b, also known as TOI-4602 b, is a sub-Neptune planet orbiting a bright and quiet star. Precise measurements of its mass and radius show that it is about 2.5 times the size of Earth and 5.5 times as massive. This places it just above the so-called radius valley, a region where few planets are found, and suggests that it is in transition between a sub-Neptune and a super-Earth. The planet's bulk density indicates that it still has a thi...
