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 …
Efficient labelling of solar flux evolution videos by a deep learning model
Chatterjee, Subhamoy; Muñoz-Jaramillo, Andrés; Lamb, Derek A.
Machine learning is becoming a critical tool for the interrogation of large, complex data. Labelling, defined as the process of adding meaningful annotations, is a crucial step of supervised machine learning. However, labelling datasets is time consuming. Here we show that convolutional neural networks (CNNs) trained on crudely labelled astronomic…
