Monitoring of PDS 110 requested to cover upcoming eclipse by exoplanet
Active Dates: Aug. 1, 2017 – Oct. 31, 2017
Abstract:
Dr. Joey Rodriguez (Harvard-Smithsonian Center for Astrophysics), Dr. Hugh Osborn (University of Warwick), Dr. Matthew Kenworthy (Leiden Observatory), and colleagues have requested AAVSO assistance in monitoring PDS 110 (HD 290380), a very interesting young star that may have a large orbiting body with an extremely large ring system (on the order of 200 times wider than that of Saturn). An eclipse of PDS 110 is expected in mid- September 2017, and monitoring is requested through October.
Justification:
"The multi-band observations requested here will provide high-cadence precise photometric observations of the potential sub-stellar ringed companion. The observations will be crucial in our follow-up analysis since they will 1) allow us to re-model the system with 3 eclipses, improving our parameters and allowing us to look for changes in the occulting body’s size and opacity. 2) The multi-band observations provide information on the grain size and distribution in the surrounding ring system. 3) Continuous monitoring of PDS 110 by the AAVSO can trigger the community when PDS 110 begins to eclipse. This trigger will allow us to increase the cadence of additional observations to support the AAVSO data."
