A giant planet candidate near Boyajian’s star may look oversized because a broad ring system surrounds it, not because the planet itself is unusually large. New atmospheric models also show why methane and carbon monoxide can vary across hot gas giants, exposing major limits in simpler predictions.

Image: Analysis of TOI-1408 planetary system reveals significant uncertainties in planet properties
The TOI-1408 system is known to host two planets in a 2:1 orbital resonance - meaning the inner planet completes two orbits for every one orbit of the outer planet - alongside a distant companion. A recent study of TESS space telescope data and ground-based observations has reassessed the system's configuration, finding that current measurements of the planets are influenced by complex factors in the data modeling. Researchers found that the likelihood functions, which represent the probabili...

Analysis of Kepler-51 planets investigates if ring systems hide their true density

Image: Analysis of Kepler-51 planets investigates if ring systems hide their true density
The Kepler-51 system contains planets with extremely low bulk densities, often described as super-puff planets. These worlds are so light for their size that they challenge current models of how planets are built. One theory suggests these planets may actually have hidden ring systems that make them appear larger than they are, thereby causing researchers to underestimate their true density. This study uses a method called asterodensity profiling...

Image: Atmospheric composition of the temperate super-Jupiter Epsilon Indi Ab revealed
Epsilon Indi Ab is a temperate super-Jupiter orbiting the star Epsilon Indi A. As one of the closest and coldest directly imaged exoplanets, it serves as a bridge for comparing the atmospheric properties of hot gas giants found around other stars with the cooler giants of our own solar system. Infrared observations have now successfully mapped the chemical makeup of its atmosphere despite the challenging light interference from its host star. ...

Image: Atmospheric analysis of LTT 9779 b reveals muted spectral features and cloud presence
LTT 9779 b is an ultrahot Neptune-sized exoplanet that occupies a rare region of space known as the hot Neptune desert, where such planets are seldom found. Despite its intense exposure to radiation from its host star, LTT 9779 b possesses a confirmed atmosphere. A new comprehensive study using data from the James Webb Space Telescope provides a detailed look at the chemical and physical characteristics of this exotic world's atmosphere. By an...

Image: Astrometric evidence identifies 29 potential outer giant planets in known exoplanet systems
Outer giant planets play a critical role in the development of planetary systems, yet their long orbital paths make them challenging to observe through traditional methods. By analyzing astrometric data from the Hipparcos and Gaia space missions, researchers have identified 29 candidate planets located far from their host stars. These findings suggest the presence of massive companions orbiting beyond the previously known planets in these systems...

Image: Observations of TRAPPIST-1 c reveal a likely airless surface without a thick atmosphere
Rocky planets orbiting Red dwarf stars present a unique challenge for observers because the stars themselves often have active surfaces that can mimic the signals of an atmosphere. A new analysis method has been developed to separate these stellar signals from potential atmospheric data. By applying this technique to four observations of the planet TRAPPIST-1 c, researchers have determined that the planet does not show evidence of a significant, ...

Image: Outer debris disk of Epsilon Eridani confirmed as nearly circular
Epsilon Eridani, a nearby orange dwarf star located about 10.5 light-years away, hosts the closest known debris disk - a ring of dust and icy rocks orbiting the star. This system also features a large planet, Epsilon Eridani b, which is similar to Jupiter. New measurements of the outer debris belt suggest it is remarkably circular and dynamically cold, meaning the particles within it have very orderly, stable orbits. To determine the shape of ...

Image: Ultrahot Neptune LTT 9779 b has clouds in its atmosphere
LTT 9779 b is a Neptune-sized planet that orbits extremely close to its parent star, placing it within the so-called hot Neptune desert - a region where such planets are rarely found due to intense stellar radiation. Observations of this planet are essential to understanding how its atmosphere manages to persist under these extreme conditions. New data from the James Webb Space Telescope provides a broad look at the chemical and physical characte...

Image: Cold sub-Neptune TOI-6981 b discovered orbiting near the water ice line
A new sub-Neptune planet, TOI-6981 b (LSPM J0804+1116 b), has been identified orbiting a Red dwarf star. The planet is notable for its cold temperature of approximately 170 Kelvin (minus 103 degrees Celsius), which positions it at the water ice line. This is the boundary in a star system where it is cold enough for water vapor to condense into solid ice. Its unique location and characteristics offer a rare opportunity to study cold planetary atmo...

Image: Masses and orbits of young giant planets in the HIP 67522 system measured
HIP 67522 is a young star system, aged only 17 million years, which hosts two giant planets. By observing the timing of when these planets cross in front of their host star—an event known as a transit—researchers can detect subtle shifts in the schedule caused by the gravitational tugging between the two worlds. These variations in timing, known as transit timing variations, serve as a precise tool for calculating the masses and orbital character...
