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…
Gaia-ESO Survey: massive stars in the Carina Nebula. A new census of OB stars
S. R. Berlanas, J. Maíz Apellániz, A. Herrero +16
The Gaia-ESO survey sample of massive OB stars in the Carina Nebula consists of 234 stars. The addition of brighter sources from the Galactic O-Star Spectroscopic Survey and additi…
ALMA-IMF III -- Investigating the origin of stellar masses: Top-heavy core mass function in the W43-MM2&MM3 mini-starburst
Y. Pouteau, F. Motte, T. Nony +35
The ALMA-IMF Large Program observed the W43-MM2-MM3 ridge, whose 1.3mm and 3mm ALMA 12m array continuum images reach a 2500au spatial resolution. We used both the best-sensitivity…
Escape from the Bermuda cluster: orphanization by multiple stellar ejections
J. Maíz Apellániz, M. Pantaleoni González, R. H. Barbá +1
CONTEXT. Dynamical interactions in young stellar clusters can eject massive stars early in their lives and significantly alter their mass functions. If all of the most massive star…
The Villafranca catalog of Galactic OB groups. II. From Gaia DR2 to EDR3 and ten new systems with O stars
J. Maíz Apellániz, R. H. Barbá, R. Fernández Aranda +4
CONTEXT. This is the second paper of a series on Galactic OB groups that uses astrometric and photometric data from Gaia and spectral classifications from GOSSS and LiLiMaRlin. The…
The Gaia photometric calibration and results on Galactic runaways
J. Maíz Apellániz, M. Pantaleoni González, D. J. Lennon +2
We present results on two different Gaia-related topics. First, we describe our efforts to calibrate the three Gaia photometric passbands G, G_BP, and G_RP. We have built a new spe…
Multi-band high resolution spectroscopy rules out the hot Jupiter BD+20 1790b - First data from the GIARPS Commissioning
I. Carleo, S. Benatti, A. F. Lanza +51
Context. Stellar activity is currently challenging the detection of young planets via the radial velocity (RV) technique. Aims. We attempt to definitively discriminate the nature o…
Neutrinoless double beta decay and QCD running at low energy scales
Marcela González, Martin Hirsch, Sergey Kovalenko
There is a common belief that the main uncertainties in the theoretical analysis of neutrinoless double beta () decay originate from the nuclear matrix elements. Here, we unc…
Analysis of the Kinematic Structure of the Cygnus OB1 association
M. T. Costado, E. J. Alfaro, M. Gonzalez +1
The main objective of this study is the characterization of the velocity field in the Cygnus OB1 association using the radial velocity data currently available in the literature. T…
QCD running in neutrinoless double beta decay: Short-range mechanisms
M. González, M. Hirsch, S. G. Kovalenko
The decay rate of neutrinoless double beta () decay contains terms from heavy particle exchange, which lead to dimension-9 (d=9) six fermion operators at low energies. Limits…
