But the method requires very precise measurements over long periods of time, and until now, has failed to turn up any exoplanets.
ISLAMABAD, April 29, 2009 (Balochistan Times) -- Stars eat the exoplanets that venture near them, say astronomers.
Even though COROT-9b is cooler than many other exoplanets, it's probably not habitable.
Among specific topics are Keplerian orbits and dynamics of exoplanets, transits and occultations, tidal evolution of exoplanets, giant planet formation, and terrestrial planet atmospheres and biosignatures.
The study of exoplanets is a fast-evolving branch of astronomy which has spawned a number of new books during the past few years: this from Chris Kitchin, writer and Emeritus Professor of Astronomy at the University of Hertfordshire, being one of the very latest.
The team took follow-up spectra of more than 400 stars hosting over 600 exoplanets.
Most of the detected exoplanets are gas giants, many of which are in the habitable zone," co author Suman Satyal said.
TESS s science goal is to detect transiting exoplanets orbiting nearby bright stars.
Previously, researchers had found water only on exoplanets about the size of Jupiter.
The ambitious endeavor, dubbed the Nexus for Exoplanet System Science (NExSS), deals with the study of exoplanets -- or planets around other stars.
But the novel method of detecting the planet's development through H-alpha light gives researchers a new tool to observe forming exoplanets elsewhere -- for determining those planets' orbits and interaction with nearby disks of dust and gas -- and it raises further questions about where, when and how planets can form around stars.
Astronomers often use the Earth as a proxy for hypothetical exoplanets in computer modeling to simulate what such worlds might be like and under what circumstances they might be hospitable to life.
