GMRT Radio Exoplanet Host Campaign
 |
| Two of the 38 wire dishes that make up the Giant Metre Radio Telescope (GMRT) in Khodad village, Pune, India |
We have been contacted by Dr. Joseph Lazio (U.S. Naval Research Laboratory), Paul Shankland (U.S. Naval Observatory) and Greg Laughlin (U.C. Santa Cruz) to provide support for a campaign to observe stars known to have
exoplanetary systems. While none of these stars are known to have transiting systems, exploring them can still reveal much about exoplanets and their interaction with their host stars. Dr. Lazio will be observing these
systems over the next month with the Giant Metrewave Radio Telescope (GMRT) in Pune, India.
It is not known what will be detected during these observations.
One possible result could be the detection of auroral activity around
the planet(s) and/or other types of dusty debris in the system. As a
result of this ambiguity, high precision optical observations are
needed. There may be some events seen in the optical which precede
what is detected in the radio.
.
For more specific information regarding this campaign, please see CCDViews 332 and
the joint Transitsearch-AAVSO announcement by Paul Shankland.
