PublicationA Bayesian estimation of the Milky Way's circular velocity curve using Gaia DR3
Aims: Our goal is to calculate the circular velocity curve of the Milky Way, along with corresponding uncertainties that quantify various sources of systematic...

PublicationA binary merger origin for inflated hot Jupiter planets
We hypothesize that hot Jupiters with inflated sizes represent a separate planet formation channel, the merging of two low-mass stars. We show that the...

PublicationA bipolar-outflow object in the field of M 36.
We have discovered an object in the field of the Galactic open cluster [1]36 which exhibits a nebulous tail-like structure and a high velocity outflow. We first...

PublicationA boxy bulge in the Milky Way. Inversion of the stellar statistics equation with 2MASS data
Inverting the stellar statistics equation from 2MASS star counts, we obtain the 3D density distribution of the Galactic bulge as well as its luminosity function...

PublicationA calibration of the Rossby number from asteroseismology
Stellar activity and rotation are tightly related in a dynamo process. Our understanding of this mechanism is mainly limited by our capability of inferring the...

PublicationA candidate short-period sub-Earth orbiting Proxima Centauri
Context. Proxima Centauri is the closest star to the Sun. This small, low-mass, mid M dwarf is known to host an Earth-mass exoplanet with an orbital period of...

PublicationA case against an X-shaped structure in the Milky Way young bulge
Context. A number of recent papers have claimed the discovery of an X-shape structure in the bulge of our Galaxy in the population of the red clumps. Aims: We...

PublicationA catalog of warps in spiral and lenticular galaxies in the Southern hemisphere
A catalog of optical warps of galaxies is presented. This can be considered complementary to that reported by Sánchez-Saavedra et al. (cite{sanchez-saavedra})...
