A deep-learning search for technosignatures from 820 nearby stars
de Pater, Imke; Gajjar, Vishal; Siemion, Andrew P. V. +14 more
The goal of the search for extraterrestrial intelligence (SETI) is to quantify the prevalence of technological life beyond Earth via their `technosignatures'. One theorized technosignature is narrowband Doppler drifting radio signals. The principal challenge in conducting SETI in the radio domain is developing a generalized technique to reject hum…
A spectroscopic quadruple as a possible progenitor of sub-Chandrasekhar type Ia supernovae
Zwitter, Tomaž; Traven, Gregor; Gilmore, Gerry +13 more
Binaries have received much attention as possible progenitors of type Ia supernova explosions1, but long-term gravitational effects2,3 in tight triple or quadruple systems could also play a key role in producing type Ia supernovae. Here we report on the properties of a spectroscopic quadruple found within a star cluster: the …
The mass of the young planet Beta Pictoris b through the astrometric motion of its host star
Snellen, I. A. G.; Brown, A. G. A.
The young massive Jupiters discovered with high-contrast imaging1-4 provide a unique opportunity to study the formation and early evolution of gas giant planets. A key question is to what extent gravitational energy from accreted gas contributes to the internal energy of a newly formed planet. This has led to a range of formation scenar…
