The rotation of a star and the revolutions of its planets are not necessarily aligned. This
article reviews the measurement techniques, key findings, and theoretical interpretations …

Astrophysical fluid bodies that orbit close to one another induce tidal distortions and flows
that are subject to dissipative processes. The spin and orbital motions undergo a coupled …

ImageJ is a graphical user interface (GUI) driven, public domain, Java-based, software
package for general image processing traditionally used mainly in life sciences fields. The …

We present empirical measurements of the radii of 116 stars that host transiting planets.
These radii are determined using only direct observables—the bolometric flux at Earth, the …

We present a new method to detect planetary transits from time-series photometry, the transit
least squares (TLS) algorithm. TLS searches for transit-like features while taking the stellar …

Population studies of exoplanets are key to unlocking their statistical properties. So far, the
inferred properties have been mostly limited to planetary, orbital, and stellar parameters …

We combine optical, near-infrared, and mid-infrared spectra and photometry to construct
expanded spectral energy distributions for 145 field age (> 500 Myr) and 53 young (lower …

The amount of ultraviolet irradiation and ablation experienced by a planet depends strongly
on the temperature of its host star. Of the thousands of extrasolar planets now known, only …

We present analysis of the atmospheres of 70 gaseous extrasolar planets via transit
spectroscopy with Hubble's Wide Field Camera 3 (WFC3). For over half of these, we …

We report the development of a four-color simultaneous camera for the 1.52-m Telescopio
Carlos Sánchez in the Teide Observatory, Canaries, Spain. The instrument, named …
