Looking to the future of exo-Earth imaging from the ground, core technology developments are required in visible extreme adaptive optics (ExAO) to enable the observation of atmospheric features such as […]
Estimates of the size of the feeding zone of the planet Proxima Centauri c have been made at initial orbital eccentricities of planetesimals equal to 0.02 or 0.15.
Editor’s note: one of the prime interests in the Proxima Centauri system (in addition to its proximity to Earth) is the presence of at least one of three detected planets […]
Proxima Centauri is the closest star to the Sun. This small, low-mass, mid M dwarf is known to host an Earth-mass exoplanet with an orbital period of 11.2 days within […]
A team of scientists, including Arizona State University’s Evgenya Shkolnik and Parke Loyd, has spotted the largest flare ever recorded from the sun’s nearest stellar neighbor in ultraviolet light, the […]
Fritz Benedict has used data he took over two decades ago with Hubble Space Telescope to confirm the existence of another planet around the Sun’s nearest neighbor, Proxima Centauri, and […]
The existence of a planet the size of Earth around the closest star in the solar system, Proxima Centauri, has been confirmed by an international team of scientists including researchers […]
Which of Earth’s features were essential for the origin and sustenance of life? And how do scientists identify those features on other worlds? A team of investigators with array of […]
We report the observation on UT 2017.07.01 of an unusually powerful flare detected in near-infrared continuum photometry of Proxima Centauri. During a campaign monitoring the star for possible exoplanet transits, […]
Proxima Centauri was recently discovered to host an Earth-mass planet of Proxima b, and a 215-day signal which is probably a potential planet c. In this work, we investigate the […]
