The detection of anomalies in gravitational microlensing events is nowadays one of the main goals among the microlensing community. In the case of single-lens events, these anomalies can be caused […]

About Exobiology: The Case for Dwarf K Stars
One of the most fundamental topics of exobiology concerns the identification of stars with environments consistent with life. Although it is believed that most types of main-sequence stars might be […]
EXPRES: A Next Generation RV Spectrograph in the Search for Earth-like Worlds
The EXtreme PREcision Spectrograph (EXPRES) is an optical fiber fed echelle instrument being designed and built at the Yale Exoplanet Laboratory to be installed on the 4.3-meter Discovery Channel Telescope […]
Cloudy Days on Exoplanets May Hide Atmospheric Water
Water is a hot topic in the study of exoplanets, including “hot Jupiters,” whose masses are similar to that of Jupiter, but which are much closer to their parent star […]
Hot Atmospheres Could Limit Number of Habitable Planets
New research has revealed that fewer than predicted planets may be capable of harbouring life because their atmospheres keep them too hot. An international team describe the work in a […]
Planet 1,200 Light-years Away Is A Good Prospect For Habitability
A distant planet known as Kepler-62f could be habitable, a team of astronomers reports. The planet, which is about 1,200 light-years from Earth in the direction of the constellation Lyra, […]
Habitable Worlds With JWST: Transit Spectroscopy of the TRAPPIST-1 System?
The recent discovery of three Earth-sized, potentially habitable planets around a nearby cool star, TRAPPIST-1, has provided three key targets for the upcoming James Webb Space Telescope (JWST). Depending on […]
Impact of Secular Resonances on Habitable Zones in Circumstellar Planetary Systems of Known Binary Stars
We present a survey on binary star systems with stellar separations less than 100 astronomical units. For a selection of 11 binaries with a detected (giant) planet in circumstellar motion […]
Using Kepler Candidates to Examine the Properties of Habitable Zone Exoplanets
An analysis of the currently known exoplanets in the habitable zones (HZs) of their host stars is of interest in both the wake of the NASA Kepler mission and with […]
Limit Cycles Can Reduce The Width of the Habitable Zone
The liquid water habitable zone (HZ) describes the orbital distance at which a terrestrial planet can maintain above-freezing conditions through regulation by the carbonate-silicate cycle. Recent calculations have suggested that […]
