Yearslong time series of high-precision brightness measurements have been assembled for
thousands of stars with telescopes operating in space. Such data have allowed astronomers …

We describe the catalogs assembled and the algorithms used to populate the revised TESS
Input Catalog (TIC), based on the incorporation of the Gaia second data release. We also …

Abstract We introduce the Automatic Learning for the Rapid Classification of Events
(ALeRCE) broker, an astronomical alert broker designed to provide a rapid and self …

Gaia Data Release 3 provides novel flux-calibrated low-resolution spectrophotometry for≃
220 million sources in the wavelength range 330 nm≤ λ≤ 1050 nm (XP spectra). Synthetic …

Context. Gaia DR3 contains 1.8 billion sources with G-band photometry, 1.5 billion of which
with G BP and G RP photometry, complemented by positions on the sky, parallax, and …

Increasingly, uncertainties in predictions from galaxy formation simulations (at sub-Milky
Way masses) are dominated by uncertainties in stellar evolution inputs. In this paper, we …

Context. RR Lyrae stars are excellent tracers of the oldest stars (ages≳ 9–10 Gyr) and
standard candles for measuring the distance to stellar systems that are mainly composed of …

Context. Gaia Early Data Release 3 (Gaia EDR3) contains astrometry and photometry
results for about 1.8 billion sources based on observations collected by the European Space …

Aims. We perform a comprehensive determination of the systemic proper motions of 74
dwarf galaxies and dwarf galaxy candidates in the Local Group based on Gaia early data …

Context. Cepheids are pulsating stars that play a crucial role in several astrophysical
contexts. Among the different types, the Classical Cepheids are fundamental tools for the …
