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 …

Stellar multiplicity is a ubiquitous outcome of the star-formation process. The frequency and
main characteristics of multiple systems, and their dependence on primary mass and …

Identifying terrestrial planets in the habitable zones (HZs) of other stars is one of the primary
goals of ongoing radial velocity (RV) and transit exoplanet surveys and proposed future …

The Kepler mission, combined with ground-based radial velocity (RV) follow-up and
dynamical analyses of transit timing variations, has revolutionized the observational …

We describe the contents and functionality of the NASA Exoplanet Archive, a database and
toolset funded by NASA to support astronomers in the exoplanet community. The current …

HIV-1 entry into CD4+ target cells is mediated by cleaved envelope glycoprotein (Env)
trimers that have been challenging to characterize structurally. Here, we describe the crystal …

Transiting planet surveys like Kepler have provided a wealth of information on the
distribution of planetary radii, particularly for the new populations of super-Earth-and sub …

Abstract We present the Open Supernova Catalog, an online collection of observations and
metadata for presently 36,000+ supernovae and related candidates. The catalog is freely …

We present EXOFAST, a fast, robust suite of routines written in IDL that is designed to fit
exoplanetary transits and radial velocity variations simultaneously or separately and …

The ongoing discoveries of extra-solar planets are unveiling a wide range of terrestrial mass
(size) planets around their host stars. In this Letter, we present estimates of habitable zones …
