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: Inflated hot Neptune TOI-2195 A b likely formed from a massive gas giant
A newly identified planet, TOI-2195 A b, has been found orbiting an orange dwarf star. Classified as an inflated hot Neptune, this planet completes an orbit around its host star every 4.16 days. The discovery offers a new perspective on how such planets form, suggesting they may have once been much larger gas giants that lost a significant portion of their mass. Researchers analyzed the system using the Rossiter-McLaughlin effect, which measures the change in light as a planet transits a rota...

Image: Atmosphere of planet WD 1856 b contains hydrocarbons and aerosols
White dwarfs are the dense, cooling remnants of stars like our Sun. While it is known that some planets can survive the violent evolution of their host star into a white dwarf, little is known about the makeup of their atmospheres. Observations of the planet WD 1856 b now reveal an atmosphere containing hydrocarbons and aerosols, along with unexpectedly high temperatures, offering new insights into how these planets survive and evolve long after ...

Image: TESS detects first bound microlensing planet orbiting an orange dwarf in Gaia23bra
The Transiting Exoplanet Survey Satellite (TESS) has successfully identified its first gravitationally bound planet through a technique known as microlensing. Microlensing occurs when the gravity of a star and its orbiting planet acts like a magnifying glass, bending and brightening the light of a more distant background star as the system passes in front of it. The newly characterized planet, designated Gaia23bra b, orbits an orange dwarf star. ...

Image: CHEOPS observations reveal planetary densities and atmospheric evolution in V1298 Tau system
The young V1298 Tau planetary system, estimated to be between 10 and 30 million years old, provides a window into the early stages of planet formation. Recent observations focused on the three innermost planets of the system, refining measurements of their sizes and physical properties to better understand how young worlds develop their atmospheres and internal structures. Data from the CHEOPS space telescope allowed for high-precision measure...

Image: Two low density giant planets found orbiting the star TOI-791
Two giant planets, TOI-791 b and TOI-791 c, have been confirmed orbiting the F7-type star TOI-791. Both planets are similar in size to Jupiter, but they possess exceptionally low densities. They follow long-period orbits, taking approximately 139 days and 232 days respectively to complete a revolution around their host star. The planets are locked in a orbital relationship known as a 5:3 resonance, which causes detectable timing shifts as they pa...

Image: High-resolution observations reveal reflected light from ultra-hot exo-Neptune LTT 9779 b
The ultra-hot Neptune-mass planet LTT 9779 b has been studied through the detection of its reflected starlight. Because planets are much fainter than their host stars, capturing the light they reflect is a significant technical challenge. By observing the system at high spectral resolution, investigators were able to isolate the faint signal of light bouncing off the planet, providing new information about its atmosphere. The findings were gat...

Image: Compact planetary system TOI-1533 hosts two unique super-Neptune planets
The planetary system TOI-1533 consists of two planets orbiting an active orange dwarf star. Located in a compact arrangement, this system features an inner sub-Neptune planet and an outer, larger hot giant planet. Such systems, where a large gas-rich planet is accompanied by a smaller companion, are rare and provide insight into how planetary systems migrate and evolve over time. The research reveals that both planets transit, or pass in front...

The temperate exo-Neptune TOI-1231 b serves as a vital benchmark for understanding planets smaller than Neptune. Because of its density, the planet is known to possess a deep, hydrogen-rich atmosphere. This study provides the first near-infrared transmission spectrum—a technique that analyzes how starlight filters through a planet's atmosphere—to determine its chemical makeup, offering a reference for similar worlds. Researchers identified a s...

The TOI-2134 planetary system contains two confirmed planets orbiting their host star. The inner planet is a mini-Neptune, a gas-rich world smaller than Neptune, while the outer planet is a temperate sub-Saturn. By combining new observations from the TESS space telescope with extensive ground-based velocity measurements, the composition and orbital paths of these planets have been precisely determined, revealing a complex system architecture. ...

Image: Observations of PDS 70 reveal new dust clumps and potential third planet
The young star PDS 70 is known to host two confirmed protoplanets within its disk of gas and dust. Recent observations have identified two elongated dust features near the star, which may indicate the presence of a previously unknown third planet or complex structures within the inner disk. These features share the same orbit, with one leading the other by approximately 120 degrees, suggesting they could be dust trapped by the gravity of an unsee...
