We present the Young Exoplanet Transit Initiative (YETI), in which we use several 0.2 to 2.6-m telescopes around the world to monitor continuously young (≤100...
The young HD 73583 (TOI-560) planetary system: two 10-M<SUB>⊕</SUB> mini-Neptunes transiting a 500-Myr-old, bright, and active K dwarf
We present the discovery and characterization of two transiting planets observed by TESS in the light curves of the young and bright (V = 9.67) star HD73583...
The young massive SMC cluster NGC 330 seen by MUSE. I. Observations and stellar content
Context. A majority of massive stars are part of binary systems, a large fraction of which will inevitably interact during their lives. Binary-interaction...
The young open cluster NGC 7067 using Strömgren photometry
NGC 7067 is a young open cluster located in the direction between the first and the second Galactic quadrants and close to the Perseus spiral arm. This makes it...
The young stellar population of IC 1613. I. A new catalogue of OB associations
Context: Determining the parameters of massive stars is crucial to understand many processes in galaxies and the Universe, since these objects are important...
The young stellar population of IC 1613. II. Physical properties of OB associations
Context. To understand the structure and evolution of massive stars, systematic surveys of the Local Group galaxies have been undertaken, to find these objects...
The young stellar population of IC 1613. III. New O-type stars unveiled by GTC-OSIRIS
Context. Very low-metallicity massive stars are key to understanding the reionization epoch. Radiation-driven winds, chief agents in the evolution of massive...
The Young, Massive, Star Cluster Sandage-96 After the Explosion of Supernova 2004dj in NGC 2403
The bright Type II-plateau supernova (SN) 2004dj occurred within the young, massive stellar cluster Sandage-96 in a spiral arm of NGC 2403. New multiwavelength...
The z = 5 Quasar Luminosity Function from SDSS Stripe 82
We present a measurement of the Type I quasar luminosity function at z = 5 using a large sample of spectroscopically confirmed quasars selected from optical...
