Chemical modelling of interstellar MgS
M. Rey-Montejo, I. Jimenez-Serra, T. Millar +8
The detection of magnesium sulphide (MgS) and sodium sulphide (NaS) towards the Galactic Center molecular cloud G+0.693 constitutes the first detection of metal sulphides in the in…
The Galactic Centre G+0.633-0.0604 molecular cloud: a new astrochemical gold mine. I. Gas physical properties
D. San Andrés, L. Colzi, V. M. Rivilla +4
In the Central Molecular Zone (CMZ), shocks play a key role in triggering star formation and driving chemical enrichment. The Sgr B2 complex is a prime template, hosting massive pr…
Evolution of Chemistry in the envelope of HOt corinoS (ECHOS). III. Sulphur chemistry in the Class 0 objects HH 212 and NGC 1333 IRAS 4A
P. Fernández-Ruiz, A. Fuente, G. Esplugues +7
Our goal is to find chemical diagnostics to determine the physical conditions in protostellar envelopes and help establish the development of matter during the formation of a low-m…
The small transiting planet population revealed by ESPRESSO with extreme precision radial velocities
M. J. Hobson, B. Lavie, F. Bouchy +35
Small planets are extremely common in the Galaxy, including planets with masses and radii between those of Earth and Neptune. Characterizing these planets' masses requires ultra-pr…
Sailing to the next safe harbour in our trip to the early Universe: The massive star population of metal-poor galaxies
N. Castro, M. Garcia, A. Herrero +5
Very metal-poor massive stars in the Local Group are our best proxies for the Universe's first stars, making them essential for modeling reionization and early galactic chemical ev…
Investigating episodic mass loss in evolved massive stars IV. Comprehensive analysis of dusty red supergiants in NGC 6822, IC 10, and WLM
E. Christodoulou, S. de Wit, A. Z. Bonanos +6
Mass loss shapes the fate of massive stars; however, the physical mechanism causing it remains uncertain. We present a comprehensive analysis of seven red supergiants, for which we…
