Full 3-D view of Binary Star-Planet System

Astronomers using the VLBA have produced a full, 3-D view of a binary star system with a planet orbiting one of the stars. Their achievement promises important new insights into the process of planet formation.

By precisely tracing a small, almost imperceptible, wobble in a nearby star’s motion through space, astronomers have discovered a Jupiter-like planet orbiting that star, which is one of a binary pair. Their work, using the National Science Foundation’s Very Long Baseline Array (VLBA), produced the first-ever determination of the complete, 3-dimensional structure of the orbits of a binary pair of stars and a planet orbiting one of them...

The Dark side of Extrasolar planets share surprisingly Similar Temperatures

Schematic of clouds on the night side of a hot Jupiter exoplanet. The underlying atmosphere is over 800 C, hot enough to vaporize rocks. Atmospheric motion from the deep atmosphere or from the hotter dayside bring the rock vapour to cooler regions, where it condenses into clouds, and possibly rains down into the atmosphere below. These clouds of condensed rock block outgoing thermal radiation, making the planet’s nightside appear relatively cool from space.

New study suggests that the nightsides of hot Jupiters share clouds made of minerals...

An international team of astronomers using a combination of ground and space based telescopes have reported more than 100 extrasolar planets (here after, exoplanets) in only three months. These planets are quite diverse and expected to play a large role in developing the research field of exoplanets and life in the Universe.

Exoplanets, planets that revolve around stars other than the Sun, have been actively researched in recent years. One of the reasons is the success of the Kepler Space Telescope, which launched in 2009 to search for exoplanets...

Looking for Extrasolar planets: DARKNESS lights the way

Physicists and astronomers commission the most advanced superconducting camera in the world. Somewhere in the vastness of the universe another habitable planet likely exists. And it may not be that far – astronomically speaking – from our own solar system. Distinguishing that planet’s light from its star, however, can be problematic. But an international team led by UC Santa Barbara physicist Benjamin Mazin has developed a new instrument to detect planets around the nearest stars. It is the world’s largest and most advanced superconducting camera...
