A new unreviewed study claims that black holes can burp up star remnants several years after they eat them.
TDEs typically manifest whenever a star comes too close to a black hole. The gravitational pull of the black hole results in the exertion of extreme tidal forces on stars, essentially ripping them to shreds. Any stars that are unlucky enough to fall into a black hole experience a rapid process of disintegration. This event is accompanied by a significant release of electromagnetic radiation in the visible light spectrum.
This leftover material coalesces into a thin, disk-shaped structure, which scientists call an accretion disk, while a portion of the rest of the shattered star is blasted away from the black hole. In turn, this disk makes the gradual transport of matter to the black hole easier. The accretion disk experiences instability early in its inception, which causes material inside the disk to move and collide.
“If you look years later, a very, very large fraction of these black holes that don’t have radio emission at these early times will actually suddenly ‘turn on’ in radio waves,” Yvette Cendes, a research associate at the Havard and Smithsonian Center for Astrophysics, and lead author on a new study toldOf course, the term “burp” is used here to describe the process that happens after the TDE has passed when remnants of the star are literally ejected from the black hole.

Researchers discover key functions of plasma membrane–cell wall adhesion in rice and critical genes involvedIn a study published in Nature Plants, a research team led by Prof. Chao Daiyin from the Center of Excellence for Molecular Plant Sciences of the Chinese Academy of Sciences identified a novel protein family in plants named as GAPLESS, and revealed that members of this family mediate the adhesion between the cell wall and the plasma membrane at the Casparian strip (CS), a barrier in the root endodermis. This adhesion plays a critical role in controlling nutrient transport and the growth development of rice.
