Stars | Exoplanets | Planet formatioThe protoplanetary disk surrounding the star HD 163296 contains complex structures that provide insight into the birthplace of planets. By analyzing new and archival data from the Atacama Large Millimeter/submillimeter Array (ALMA), researchers have characterized the temperature, density, and size of dust grains within this vast cloud of gas and debris.
To study the disk, the analysis utilized spectral energy distribution fitting, a technique that examines how light is emitted across differen...

1. 8. 2026Stars | Exoplanets | Young Stellar ObjeThe WISPIT 2 system, known for harboring two giant protoplanets within a multi-ringed disc of gas and dust, has been identified as a spectroscopic binary. This means the system consists of two stars orbiting one another, visible through changes in their light patterns rather than direct imaging of both stars. This discovery establishes the system as a primary location for studying how planets form in environments around two stars.
The system c...
Read article 1. 8. 2026Stars | Exoplanets | James Webb Space Telescope | Young Stellar Objects | Planet formatioThe protoplanetary disk surrounding the star TW Hydrae, the nearest such disk to Earth, has been observed in unprecedented detail. Protoplanetary disks are rotating, flattened clouds of gas and dust that surround young stars, serving as the raw material for planet formation. By using the high-contrast imaging capabilities of the James Webb Space Telescope’s Near Infrared Camera, researchers have mapped the disk's architecture to better understand...
Read article 1. 8. 2026Stars | Exoplanets | Brown dwarfRadio waves emitted by ultra-cool dwarf stars suggest these objects possess radiation belts similar to those found around Jupiter. These belts consist of plasma, a state of matter containing charged particles, trapped within the star's magnetic field. This study investigates the origin of this plasma for the ultra-cool dwarf LSR J1835+3259 by modeling potential sources, such as escaping atmospheric ions or material from a volcanic moon.
The re...
Read article 1. 8. 2026Stars | Exoplanets | Planet formatioThe red dwarf star AU Microscopii is surrounded by a complex debris disk—a ring of dust and rocky debris—that features unusual clumps of dust moving at high speeds. These features, visible only when scattering light from the star, consist of tiny grains about 0.2 micrometers in size. New simulations suggest that the observed motion of these dust clumps may be caused by the gravitational influence of a yet-to-be-confirmed planet interacting with t...
Read article 1. 8. 2026Stars | Exoplanets | Planetary atmospheres | Hot JupiterWASP-178 b is an ultra-hot Jupiter, a gas giant planet that orbits extremely close to its parent star, resulting in scorching atmospheric temperatures. New high-resolution optical observations of the planet’s dayside reveal a thermal inversion, a state where the temperature in the upper atmosphere increases with altitude, opposite to the expected cooling trend. These findings help clarify the complex, three-dimensional processes driving extreme w...
Read article 7. 7. 2026Stars | Young Stellar Objects | Planet formatioCI Tauri is a young star surrounded by a protoplanetary disk—a rotating, flattened cloud of gas and dust from which planets are born. While these disks often contain rings and gaps that signal planet formation, narrow structures can be too small for telescopes to resolve directly. A new method has now revealed hidden, fine-scale features within the disk of CI Tauri by measuring how brightness changes at different angles.
The analysis focused o...
Read article 7. 7. 2026Stars | Exoplanets | Black holes | TESSThe TOI 2796 system, which is known to host a hot Jupiter—a massive gas giant planet orbiting very close to its parent star—faces potential disruption from encounters with primordial black holes. Primordial black holes are hypothetical objects thought to have formed in the very early universe, long before the first stars and galaxies emerged. Using numerical three-body simulations, the gravitational effects of such an encounter on the planetary s...
Read article 7. 7. 2026Stars | Exoplanets | Brown dwarfs | ExomooEvidence for satellites orbiting the brown dwarf CD-35 2722 B has been identified using precise light measurements. While thousands of planets have been found orbiting stars, satellites around objects outside our solar system—known as exosatellites—have remained elusive and controversial. This study presents a strong detection of at least one, and possibly two, massive objects circling this brown dwarf, providing new data on how such systems form...
Read article 6. 7. 2026Stars | Exoplanets | TESS | Orange dwarfA 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 measur...
