A new method to cleanly separate hot and cool populations using just Gaia and 2MASS photometry
J. Maíz Apellániz, M. Pantaleoni González
We have developed a photometric method that produces clean hot (intrinsically blue) populations using Gaia and 2MASS photometry alone with [a] a very small (false positives < 1%) c…
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…
Extinction, the elephant in the room that hinders optical Galactic observations
Jesús Maíz Apellániz
Extinction is the elephant in the room that almost everyone tries to avoid when analyzing optical/IR data: astronomers tend to find a quick fix for it that the referee will accept,…
X-Shooting ULLYSES: massive stars at low metallicity. I. Project Description
Jorick S. Vink, A. Mehner, P. A. Crowther +78
Observations of individual massive stars, super-luminous supernovae, gamma-ray bursts, and gravitational-wave events involving spectacular black-hole mergers, indicate that the low…
Stellar variability in Gaia DR3. I. Three-band photometric dispersions for 145 million sources
J. Maíz Apellániz, G. Holgado, M. Pantaleoni González +1
CONTEXT: The unparalleled characteristics of Gaia photometry make it an excellent choice to study stellar variability. AIMS: To measure the phot. dispersion in G+G_BP+G_RP of the 1…
The IACOB project VIII. Searching for empirical signatures of binarity in fast-rotating O-type stars
N. Britavskiy, S. Simón-Díaz, G. Holgado +6
The empirical distribution of projected rotational velocities (vsini) in massive O-type stars is characterized by a dominant slow velocity component and a tail of fast rotators. Bi…
