White dwarf collisions and the meteoritic Ne-E annomaly
Jordi Isern, Eduardo Bravo
The analysis of noble gases in primitive meteorites has shown the existence of anomalous isotopic abundances when compared with the average Solar System values. In particular it ha…
White Dwarf Collisions, a promising scenario to account for meteoritic anomalies
J. Isern, E. Bravo
It is commonly accepted that collisions between white dwarfs (WD) are rare events that only occur in the dense interior of globular clusters or in the dense outskirts around the ce…
AT 2017be - a new member of the class of Intermediate-Luminosity Red Transients
Y-Z. Cai, A. Pastorello, M. Fraser +20
We report the results of our spectrophotometric monitoring campaign for AT~2017be in NGC~2537. Its lightcurve reveals a fast rise to an optical maximum, followed by a plateau lasti…
The e-ASTROGAM gamma-ray space observatory for the multimessenger astronomy of the 2030s
V. Tatischeff, A. De Angelis, M. Tavani +74
e-ASTROGAM is a concept for a breakthrough observatory space mission carrying a gamma-ray telescope dedicated to the study of the non-thermal Universe in the photon energy range fr…
Axions and the luminosity function of white dwarfs. The thin and thick disks, and the halo
Jordi Isern, Enrique Garcia-Berro, Santiago Torres +2
The evolution of white dwarfs is a simple gravothermal process of cooling. Since the shape of their luminosity function is sensitive to the characteristic cooling time, it is possi…
SNhunt151: an explosive event inside a dense cocoon
N. Elias-Rosa, S. Benetti, E. Cappellaro +20
SNhunt151 was initially classified as a supernova (SN) impostor (nonterminal outburst of a massive star). It exhibited a slow increase in luminosity, lasting about 450 d, followed…
