Astronomers have found a #planet that orbits at an angle of 90 degrees around a rare pair of peculiar #stars.

This is the first time there is strong evidence for one of these ‘polar planets’ orbiting a stellar pair.

The unprecedented #exoplanet, named 2M1510 (AB) b, orbits a pair of young brown dwarfs.

The two brown dwarfs produce eclipses of one another as seen from Earth, making them part of what astronomers call an eclipsing binary.

My other ½ – an astrophysicist working currently in space weather – gave me this map/chart… Now I have to find someone to preserve and frame it - sheesh! ~smile~

#EinsteinProbe finds twin cannibal #stars that have spent 40 million years taking turns eating each other
Larger of two stars started to expand, as stars do late in life, and became white dwarf with same mass as sun. Second sun – which started life as smaller one - pulled in gas from its dying companion , eventually growing to become Be star that massed about 12 times more than Sol.
By this time, white dwarf's gravity meant it was able to absorb matter from Be star.

What happens when a newly formed #star captures material from a nearby cloud?

Gas, dust, and rocky materials swirl around recently formed #stars, creating a circumstellar disk that seeds the formation of #planets.

Recent observations of some of these disks reveal filamentary structures of material falling into the disk, feeding the planet-forming environment with new ingredients in a process known as “late-stage infall.”

AAS Nova · A Late-Stage Infall Renovation: Mapping the Circumstellar Disk of AB AurigaeWhat happens when a young star captures some extra gas and dust? New observations of a dusty disk reveals how a late-stage infall event may be influencing planet formation in AB Aurigae.

100 years ago, Cecilia Payne discovered what the stars are made of It might seem obvious today, but it was just 100 years ago that we discovered that the Sun, and all stars, are made of hydrogen and helium. We should thank Cecilia Payne for that. bigthink.com/starts-with-... #space #science #stars

Big Think100 years ago, Cecilia Payne discovered what the stars are made ofFor centuries, even after we knew the Sun was a star like any other, we still didn't know what it was made of. Cecilia Payne changed that.
