Abstract Stars are initially powered by the fusion of hydrogen to helium. These ashes serve as fuel in a series of stages1,2,3, transforming massive stars into a structure of shells. These are composed of natal hydrogen on the outside and consecutively heavier compositions inside, predicted to be dominated by He, C/O, O/Ne/Mg and O/Si/S (refs. 4,5). Silicon and sulfur are fused into iron, leading to the collapse of the core and either a supernova explosion or the formation of a black hole6,7,8,9.

The Zwicky Transient Facility survey publishes its long awaited sample of 3628 Type Ia Supernovae

|
By Mickael Rigault, Nicolas Leroy, Thomas Hortala
| CNRS
Important facts Type Ia Supernovae are cosmic explosions used to measure distances across the universe. In 2.5 years, ZTF has doubled the number available Type Ia Supernovae for cosmology acquired for the last 30 years (nearly 3000). The collaboration is now releasing this dataset alongside with an Special Issue in Astronomy and Astrophysics made of 21 publications.

Supernova survey and follow-up The ZTF has been monitoring the transient sky at optical wavelengths since 20189,10,11,34. SN Zwicky16 was discovered under the BTS programme15. The first detection of the SN was in a ZTF g-band image from 2022 August 1. It was saved to the BTS as an SN candidate by on-duty scanners on August 335 and subsequently assigned to the queue for spectroscopic follow-up with SEDM mounted on P60 under standard BTS protocols.

Abstract Tidal disruption events (TDEs) are bursts of electromagnetic energy that are released when supermassive black holes at the centres of galaxies violently disrupt a star that passes too close1. TDEs provide a window through which to study accretion onto supermassive black holes; in some rare cases, this accretion leads to launching of a relativistic jet2,3,4,5,6,7,8,9, but the necessary conditions are not fully understood.

Exceptionally luminous jets: when a star meets a black hole

|
By Susanna D. Vergani, Mickael Rigault, Ouns Hamdi
| CNRS
Breadcrumb Home Press Area For the first time in over a decade, scientists from the CNRS and the Institut de radioastronomie millimétrique1 , together with international colleagues, have observed a tidal disruption event (TDE) with jets, a very rare occurrence resulting from an encounter between a star and a supermassive black hole (SMBH). When such an event occurs, gravity disrupts the star: its matter breaks apart and spins quickly before being submerged by the black hole.
