Dynamics of the Great Oxidation Event from a 3D photochemical-climate model
Adam Yassin Jaziri, Benjamin Charnay, Franck Selsis +2
From the Archean toward the Proterozoic, the Earth's atmosphere underwent a major shift from anoxic to oxic conditions, around 2.4 to 2.1 Gyr, known as the Great Oxidation Event (G…
A very luminous jet from the disruption of a star by a massive black hole
Igor Andreoni, Michael W. Coughlin, Daniel A. Perley +78
Tidal disruption events (TDEs) are bursts of electromagnetic energy released when supermassive black holes (SMBHs) at the centers of galaxies violently disrupt a star that passes t…
Gravitational waves radiated by magnetic galactic binaries and detection by LISA
Adrien Bourgoin, Christophe Le Poncin-Lafitte, Stéphane Mathis +1
In the context of the future Laser Interferometer Space Antenna (LISA) mission, galactic binary systems of white dwarfs and neutron stars will represent the dominant source of Grav…
Intergranular corrosion in evolving media: experiment and modeling by cellular automata
S. Guiso, N. Brijou-Mokrani, J. de Lamare +4
We investigate the impact of the oxidizing character of the nitric medium on the evolution of the intergranular corrosion of a stainless steel. In two different oxidizing condition…
Impact of magnetism on gravitational waves emitted by compact galactic binaries in quasi-circular orbits
Adrien Bourgoin, Etienne Savalle, Christophe Le Poncin-Lafitte +3
The LISA (Laser Interferometer Space Antenna) mission will observe in the low frequency band from 0.1 mHz to 1 Hz. In this regime, we expect the galactic binaries to be the dominan…
Saturn's atmospheric response to the large influx of ring material inferred from Cassini INMS measurements
Julianne I. Moses, Zarah L. Brown, Tommi T. Koskinen +12
During the Grand Finale stage of the Cassini mission, organic-rich ring material was discovered to be flowing into Saturn's equatorial upper atmosphere at a surprisingly large rate…
