Non-negative matrix factorization: robust extraction of extended structures
We apply the vectorized non-negative matrix factorization (NMF) method to the post-
processing of the direct imaging data of exoplanetary systems such as circumstellar disks …

Exocometary gas in the HD 181327 debris ring
An increasing number of observations have shown that gaseous debris discs are not an
exception. However, until now, we only knew of cases around A stars. Here we present the …
