Sentences with phrase «forming dwarf system»

«Surprisingly, the host galaxy [of FRB 121102] is a puny, star - forming dwarf system,» says ASTRON's Cees Bassa, who led the optical observations together with Shriharsh Tendulkar of McGill University in Montreal, Canada.

Not exact matches

They soon realized the pair formed when two dwarf planets collided in the outer solar system.

Explaining an ammonia - rich Ceres may require either pushing the dwarf planet's birthplace much farther out from the sun or importing showers of ammonia - rich pebbles from the outer solar system to help form Ceres where it now resides.

Project Blue's proposed telescope would have a light - gathering mirror just half a meter wide — so small that it could only look for Earth - like planets around two stars: the Sun - like Alpha Centauri A and Alpha Centauri B, which along with the red dwarf Proxima Centauri form the nearest star system to our own at just over four light - years away.

«Asteroid ripped apart to form star's glowing ring system: Research includes first image of ring system orbiting a white dwarf.»

There's an intriguing twist, too: Jayawardhana and others have shown that young brown dwarfs generally do not have massive protoplanetary disks of gas and dust, which means that if the new object is indeed a planet, it may not have formed the same way planets in our solar system did.

Mercedes Lopez - Morales, an astronomer at the Harvard - Smithsonian Center for Astrophysics, has modeled the possibilities of magnetic fields around red dwarf planets, and a picture is gradually emerging: The planets likely form in the outer parts of their solar systems and migrate in.

Scholz's star is actually a binary system formed by a small red dwarf, with about 9 % of the mass of the Sun, around which a much less bright and smaller brown dwarf orbits.

It's not yet clear how this binary system formed, but the discovery may help redefine the line between planets and brown dwarfs — failed stars tens of times the mass of Jupiter.

Other astronomers find the detections convincing, although most reserve the name «planet» for bodies that form within a planetary system and orbit stars, says theorist Alan Boss of the Carnegie Institution of Washington in Washington, D.C. «They should call them «planetary - mass brown dwarfs,»» Boss says.

If there is ammonia on Ceres that could mean the dwarf planet formed in the outer part of the solar system, near Neptune.

There is another Barium - dwarf candidate star, Chi1 Orionis or HR 2047 (G0 V), in the same Ursa Major stellar moving group, which suggests that all three stars may have formed a multiple system until their orbital stability was disrupted when the once, brighter and bigger AGB star shed most of an estimated original mass of 2.6 Solar to reveal its white dwarf core about 30 million years ago (Porto de Mello and da Silva, 1997).

This hypothesis suggests that all three stars may have formed a multiple system until their orbital stability was disrupted when the once, brighter and bigger AGB star (HR 6094 B) shed most of an estimated original mass of 2.6 Solar to reveal its white dwarf core about 30 million years ago (Porto de Mello and da Silva, 1997).

The orbit of an Earth - like planet around the tight binary system that star Ba forms with its brown dwarf companion in the liquid water zone would have to be centered around 1.1 AU — a little farther than Earth's orbital distance around Sol — with an orbital period exceeding one Earth year.

The brown dwarf / planet system is, in turn, orbiting around «A», forming a three - object system around 1,600 lightyears away from Earth.
