Results on young stellar clusters with the WEAVE LIFU
J. Maíz Apellániz, G. Holgado, C. Fariña +1
We present the first results of two Spanish TAC programs using the WEAVE LIFU that have been obtaining data since October 2023. The first one is obtaining high-resolution multi-epo…
Why the northern hemisphere needs a 30-40 m telescope and the science at stake: Massive stars in spiral galaxies
J. Maíz Apellániz, S. Simón-Díaz, A. Herrero +5
This document discusses the three main lines expected to dominate massive-star research in the 2040s, namely: (1) The role of metallicity in stellar evolution, especially in determ…
Science Enabled by a 30-Meter-Class Telescope in the Northern Hemisphere: Massive Stars at Low Metallicity
Miriam Garcia, Artemio Herrero, Ignacio Negueruela +11
Massive stars are at the core of our observations of the Universe up to the reionization epoch, both through their intense ionizing fluxes and through the energetic end products th…
One century data of τ CMa: a (2+1)+1 system with a short-period overcontact binary and an eccentric intermediate orbit with probably no apsidal motion
Sophie Rosu, Jesús Maíz Apellániz, Luca Sciarini +4
τ Canis Majoris (CMa) is an intriguing system that has captured astronomers' attention for more than a century. The two main components Aa and Ab are two evolved O stars on a 350 y…
