Звезды | Экзопланеты | Молодые звездные объектыThe infant star V1298 Tau, only about 20 million years old, hosts a system of four transiting planets. Determining the masses of these young worlds is essential for understanding how planetary systems form and evolve. Recent observations have provided updated mass constraints for these planets by monitoring the star over four and a half years to detect the subtle gravitational wobbles they induce on their host.
Researchers analyzed over 380 high-resolution spectra to measure the radial veloci...

25. 9. 2026Звезды | Экзопланеты | Формирование планетThe Beta Pictoris debris disk—a massive ring of dust and rocky material surrounding a young star—contains a distinct structure called the Cat's Tail. By combining years of observations from the Hubble Space Telescope, researchers have captured the first visible and near-infrared light from this feature, allowing for a detailed study of the materials and origins of this unique dust formation.
Data gathered between 2012 and 2025 enabled the iden...
Read article 25. 9. 2026Звезды | ЭкзопланетыBeta Pictoris is a young, well-studied star system already known to host planets and a vast outer debris disk. New observations have provided a clearer look at the hot, fine dust orbiting very close to the star, known as exozodiacal dust. This material represents the fine, pulverized remains of collisions within the system and offers clues into the complex environment where planets and comets interact.
Using the MATISSE instrument at the Very ...

This group of stars was once part of a separate dwarf galaxy that collided with our Milky Way billions of years ago. Observations have confirmed that this brown dwarf follows a distinct, highly eccentric orbit consistent with objects that originated outside the Milky Way and w...

These theoretical particles are proposed candidates for ultralight dark matter, which could interact with light by causing birefringence, a phenomenon that rotates the polarization angle of light as it travels through space.
By examining six sets of archival near-infrared polarize...

It possesses a mass over five times that of Jupiter and is currently recognized as having the fastest predicted orbital decay of any known giant planet. Recent data from the James Webb Space Telescope and the Hubble Space Telescope have provided evidence of complex gravitational influences affecting the planet's path as it orbits its st...

By comparing data collected in 2022 and 2024, researchers observed significant changes in the amount of light emitted by carbon monoxide gas and other material, suggesting that this small star behaves like a scaled-down version of larger, younger stars known as ...

Recent observations reveal that this planet moves in a retrograde orbit, meaning it travels in the opposite direction to the rotation of its host star. This configuration is highly unusual for small planets orbiting Red dwarf stars, providing new information about how planetary systems develop and migrate over time.
To determi...
Read article 22. 9. 2026Звезды | Экзопланеты | Формирование планетThe formation of moons around giant planets depends on how these planets pull gas and dust from the surrounding disk. By modeling the young star PDS 70, researchers have investigated how material flows toward the planet PDS 70 c. The results show that large planets act as a filter, significantly changing the amount and size of dust that can actually reach the planet's own miniature disk, known as a circumplanetary disk.
To understand this proc...

This planet is currently losing its atmosphere into space through a process known as photoevaporation, where intense radiation from the host star heats the upper atmosphere, causing gas to escape. Observations show the planet is in a rapid, transformative phase of its evolutionary history.
