The advent of radial velocity (RV) and transit photometry method has resulted in the
detection of more than 5000 exoplanets since 1995. Of these detected planets, a significant …

Rocky planet compositions regulate planetary evolution by affecting core sizes, mantle
properties, and melting behaviors. Yet, quantitative treatments of this aspect of exoplanet …

ABSTRACT A major goal in the discovery and characterization of exoplanets is to identify
terrestrial-type worlds that are similar to (or otherwise distinct from) our Earth. Recent results …

We present a catalog (status 2022 July 1) of triple and higher-order systems identified
containing exoplanets based on data from the literature, including various analyses. We …

Alpha Centauri is a triple stellar system, and it contains the closest star to Earth (Proxima
Centauri). Over the last decades, the stars in Alpha Cen and their orbits have been …

Context. Elemental abundances of Sun-like stars have been shown to be crucial for
understanding the detailed properties of planets surrounding them. However, accurately …

Recent dynamical studies indicate that the possibility of an Earth-like planet around α Cen A
or B should be taken seriously. Such a planet, if it exists, would perturb the orbital astrometry …

What makes a relatively small silicate+ metal (ie “rocky”) planet like earth, orbiting a Main
Sequence dwarf star like the Sun, suitable for the origin and propagation of life? a criterion …

Prebiotic chemistry has long sought to bridge early earth geology with contemporary
biology. 1 Collectively, there has been a tacit agreement that the end-goal of prebiotic …

Astronomy has entered a new era in which a large number of exoplanets has been
discovered (more than 5500). In the search for an Earth twin, and possibly alien life …
