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…

Why the Northern Hemisphere Needs a 30-40m Telescope and the Science at Stake: from Interstellar Visitors to Planetary Defence

J. de León, N. Pinilla-Alonso, P. Tanga +49

Small Solar system Objects (SSOs) preserve the physical, chemical, and dynamical signatures of the Sun's protoplanetary disk. Upcoming surveys will discover vast numbers of new obj…

Web-based telluric correction made in Spain: spectral fitting of Vega-type telluric standards

D. de la Fuente, A. Marco, L. R. Patrick +7

Infrared spectroscopic observations from the ground must be corrected from telluric contamination to make them ready for scientific analyses. However, telluric correction is often…

New Cepheid variables in the young open clusters Berkeley 51 and Berkeley 55

M. E. Lohr, I. Negueruela, H. M. Tabernero +3

As part of a wider investigation of evolved massive stars in Galactic open clusters, we have spectroscopically identified three candidate classical Cepheids in the little-studied c…

Calibrating the metallicity of M dwarfs in wide physical binaries with F-, G-, and K- primaries - I: High-resolution spectroscopy with HERMES: stellar parameters, abundances, and kinematics

D. Montes, R. González-Peinado, H. M. Tabernero +7

We investigated almost 500 stars distributed among 193 binary or multiple systems made of late-F, G-, or early-K primaries and late-K or M dwarf companion candidates. For all of th…

Spectral type, temperature and evolutionary stage in cool supergiants

Ricardo Dorda, Ignacio Negueruela, Carlos González-Fernández +1

In recent years, temperature scales in cool supergiants (CSGs) have been disputed, and the possibility that spectral types (SpTs) do not depend primarily on temperature has been ra…
