Cha 1107-7626: The object with the lowest mass known still hosting a protoplanetary disc with active accretion and a rich organic chemistry

Ricerca

Too small to be a star, too large to be a planet, Cha 1107-7626 is the smallest known isolated object (6–10 Jupiter masses) surrounded by a protoplanetary disk rich in gas and dust, which is still actively accreting gas and hosts organic molecules such as methane and ethylene.   Brown dwarfs are fascinating objects that represent a bridge between stars

di Mario Giuseppe Guarcello    ( segui mguarce)     A recent study by a team of researchers of INAF-Astronomical Observatory of Palermo, the University of Palermo, and the University of Madrid, recently published on the Astrophysical Journal, shows that  enormous flares in the young stars in Orion are due to large magnetic loops connecting the stars and their protoplanetary disks,
