Image: Evaporating planet explains gaseous disk formation around white dwarf WD J0914+1914

The white dwarf WD J0914+1914 is surrounded by a ring of gas containing hydrogen, oxygen, and sulfur. This material originates from a nearby Neptune-like or super-puff planet—a planet with a very low density—that is losing its atmosphere due to intense radiation from the star. The escaping gas forms a disk around the star, which is then slowly pulled onto the white dwarf's surface, creating the unique light signals observed by instruments. Advanced simulations were used to model the atmos...

Image: Wide-orbit stellar companions influence formation of giant planets around Red dwarf stars

The giant planet TOI-5628Ab orbits a Red dwarf star every 4.34 days. Observations reveal that Red dwarfs with close-in giant planets are 6 times more likely to have a distant stellar companion, suggesting these neighbors influence planetary migration....

Image: Atmosphere of planet WD 1856 b contains hydrocarbons and aerosols

The atmosphere of planet WD 1856 b, orbiting a white dwarf star, contains hydrocarbons and aerosols. Data from the James Webb Space Telescope reveal the planet is significantly warmer than expected, pointing to a past reheating event during its orbital migration....

Frequently Asked Questions about nearby stars

What is the nearest star?

Nearest star is Proxima Centauri, located approximately 4.24 light-years (1.30 parsecs) from the Sun. It is part of the Alpha Centauri star system, which also includes Alpha Centauri A and Alpha Centauri B.

What are the nearest stars to Earth?

Nearest stars to Earth include the Alpha Centauri system (Alpha Centauri A, Alpha Centauri B, and Proxima Centauri), Barnard's Star, and Wolf 359. There are also brown dwarfs Luhman 16 and WISE 0855−0714.

What is the solar neighborhood?

Solar neighborhood (also Local Interstellar Cloud) is the region of interstellar space that surrounds the Sun with diameter about 15 light years. Stellar Catalog database includes all stars contained within this region.

How do astronomers measure distances to stars?

Astronomers use methods like parallax, standard candles, and redshift to measure distances to stars. Parallax is especially useful for nearby stars in our solar neighborhood, while other techniques help map the universe beyond.

Are there any exoplanets orbiting the nearest stars?

Yes, several exoplanets have been discovered orbiting the nearest stars. For example, Proxima Centauri has an exoplanet called Proxima Centauri b, which is located in the star's habitable zone and is the closest known exoplanet to Earth.

Why are the nearest stars important for astronomy and physics?

The nearest stars provide valuable laboratories for studying stellar evolution, space environments, and the fundamental physics of stars. Observing these stars helps astronomers understand the structure of our galaxy and the broader universe.

StellarGuide: Étoiles

Étoiles

Les étoiles sont d’immenses sphères de gaz chaud qui brillent en produisant de l’énergie grâce à la fusion nucléaire dans leur noyau. La plupart des étoiles sont composées principalement d’hydrogène et d’hélium. Au centre d’une étoile, la pression et la température élevées provoquent la fusion des atomes d’hydrogène en hélium, libérant ainsi une énorme quantité d’énergie sous forme de lumière et de chaleur.
