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.

Image: AB Aurigae’s disk shows complex dynamics and accretion activity
Researchers observed the protoplanetary disk around the young star AB Aurigae using near-infrared polarized imaging and H-alpha observations over several years. Their study reveals that while most of the disk follows Keplerian rotation, the inner regions (within about 60 astronomical units) show significant deviations, including sub-Keplerian motion. Two bright spiral arms inside the disk’s millimeter cavity display different dynamic behaviors, possibly linked to planet candidates within the dis...

Image: WASP-156 b’s orbit is aligned, not polar, new data show
WASP-156 b is a short-period exo-Neptune, a planet similar in size to Neptune but much closer to its star. Scientists studied the planet’s orbit using new high-precision spectroscopic and photometric observations. They measured the Rossiter-McLaughlin effect, which reveals the angle between the planet’s orbit and the star’s rotation. The results show that WASP-156 b’s orbit is well aligned with the star’s equator, with a projected obliquity of ab...

Image: Magnetic interactions found between Proxima Centauri and its planets
Proxima Centauri, the closest star to the Sun, hosts at least two planets: Proxima b and Proxima d. Using high-resolution optical observations, astronomers searched for signs of magnetic interactions between the star and its planets. They measured the star’s rotation period as about 85 days and found that Proxima Centauri experiences frequent flares, with about 5 percent of the observing time showing flare activity. Statistical analysis revealed ...

Image: Eclipse mapping with SPIRou reveals first CO signal on WASP-33b’s dayside
WASP-33b is an ultra-hot Jupiter, a giant planet orbiting very close to its star. Scientists used high-resolution spectroscopy with the SPIRou instrument to observe eight eclipses of WASP-33b, focusing on the moments when the planet passes behind its star (ingress and egress). This technique, called eclipse mapping, can reveal details about the planet’s dayside atmosphere. The team analyzed the data using advanced software and combined it with pr...

Image: GJ 710’s rare close approach highlights stellar encounters near the Sun
This study examines how often stars pass close to the Sun and puts the upcoming fly-by of GJ 710 into context. GJ 710 is expected to come within about 0.0621 parsecs (roughly 10,000 astronomical units) of the Solar System in about 1.3 million years, making it one of the closest known future encounters. The researchers analyzed the motions of nearby stars to identify both past and future close approaches within one parsec of the Sun. They correcte...

Image: Bright ancient star G256353 shows strong r-process element enrichment
Astronomers have studied four extremely metal-poor stars, which are among the oldest and most primitive in our galaxy. The main focus is on G256353, a star with a very low iron content and a strong enhancement of elements created by the rapid neutron-capture process, known as the r-process. Using high-resolution spectra from the GHOST instrument on Gemini South, the team measured the abundances of 15 neutron-capture elements in G256353. The patte...

Image: Apsidal motion in HD 152248 reveals challenges in modeling massive star interiors
HD 152248 is a massive twin binary system used to study the internal structure of stars more than twenty times the mass of the Sun. By measuring the apsidal motion—the slow rotation of the orbit’s long axis—astronomers can probe how mass is distributed inside these stars. This study uses detailed stellar models to compare predictions with observations, focusing on the internal structure constant k2, which is sensitive to the density contrast betw...

Image: Cold Saturn-mass planet HD 38973 b found orbiting a Sun-like star
HD 38973 is a nearby star similar to the Sun. Astronomers have discovered a planet, HD 38973 b, orbiting this star with a long period of about 2733 days, or roughly 7.5 years. The planet’s mass is estimated to be about a quarter that of Jupiter, placing it in the category of cold Saturns—planets with similar mass and temperature to Saturn in our solar system. The discovery was made using precise measurements of the star’s motion, which revealed t...

Image: No radio polarization detected in colliding-wind binaries WR 147 and HD 167971
WR 147 and HD 167971 are massive star systems where strong stellar winds collide, accelerating particles to high energies. These systems, known as particle-accelerating colliding-wind binaries (PACWBs), are expected to produce synchrotron radiation in the radio range, which should be linearly polarized. However, no such polarization has been detected so far. In this study, astronomers used the Very Large Array radio telescope to observe both syst...

Image: CoRoT-2b’s dayside reveals water and carbon monoxide in complex atmosphere
CoRoT-2b is a young and unusual hot Jupiter, a giant planet orbiting very close to its star. Using the IGRINS spectrograph on the Gemini South telescope, scientists observed the planet’s dayside just before it passed behind its star. By analyzing the planet’s thermal emission, they detected clear signs of water vapor and carbon monoxide in its atmosphere. The water signal was found with high confidence, and the carbon monoxide was also detected, ...
