Context. The VLT-FLAMES Tarantula Survey has an extensive view of the copious number of massive stars in the 30 Doradus (30 Dor) star forming region of the Large Magellanic Cloud. These stars play a crucial role in our understanding of the stellar feedback in more distant, unresolved star forming regions. Aims: The first comprehensive census of hot

Near-Earth asteroid (162173) 1999 JU3 (henceforth JU3) is a potentially hazardous asteroid and the target of the Japanese Aerospace Exploration Agency’s Hayabusa-2 sample return mission. JU3 is also a backup target for two other sample return missions: NASA’s OSIRIS-REx and the European Space Agency’s Marco Polo-R. We use dynamical information to

Context. Galaxies, which often contain ionised gas, sometimes also exhibit a so-called low-ionisation nuclear emission line region (LINER). For 30 years, this was attributed to a central mass-accreting supermassive black hole (more commonly known as active galactic nucleus, AGN) of low luminosity, making LINER galaxies the largest AGN sub

The dynamics of the solar radiative interior are still poorly constrained by comparison to the convective zone. This disparity is even more marked when we attempt to derive meaningful temporal variations. Many data sets contain a small number of modes that are sensitive to the inner layers of the Sun, but we found that the estimates of their

Los centros de las galaxias muestran algunos de los extremos más fascinantes de la naturaleza. Se puede encontrar en ellos: altas concentraciones estelares, agujeros negros supermasivos, altas concentraciones de gas, fuertes campos magnéticos, poblaciones estelares no convencionales, explosiones de formación estelar, etc. Se piensa que estas
