The basic geometry of the Solar System—the shapes, spacings, and orientations of the
planetary orbits—has long been a subject of fascination as well as inspiration for planet …

Unlike most other planet-detection techniques, gravitational microlensing does not rely on
detection of photons from either the host or the planet. Rather, planets are discovered by …

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 …

We present both the technical overview and main science drivers of the fourth phase of the
Optical Gravitational Lensing Experiment (hereafter OGLE-IV). OGLE-IV is currently one of …

Abstract The Transiting Exoplanet Survey Satellite (TESS) has a goal of detecting small
planets orbiting stars bright enough for mass determination via ground-based radial velocity …

The riddle posed by super-Earths (1–4R⊕, 2–20M⊕) is that they are not Jupiters: their core
masses are large enough to trigger runaway gas accretion, yet somehow super-Earths …

We combine VI photometry from OGLE-III with VISTA Variables in The Via Lactea survey and
Two Micron All Sky Survey measurements of E (J− K s) to resolve the longstanding problem …

Since 1995, more than 500 exoplanets have been detected using different techniques,, of
which 12 were detected with gravitational microlensing,. Most of these are gravitationally …

Context. Planet formation is sensitive to the conditions in protoplanetary disks, for which
scaling laws as a function of stellar mass are known. Aims. We aim to test whether the …

Most known extrasolar planets (exoplanets) have been discovered using the radial velocity,
or transit methods. Both are biased towards planets that are relatively close to their parent …
