Dr. Alex Wolszczan

Dr. Alex Wolszczan, who is a professor at Penn State and a long-term user, visited the Arecibo Observatory during the week of March 4th, 2019 as part of an observing campaign to search for radio emission from cool brown dwarfs.

During this visit, Alex spoke about the possibility of detecting such planets via flaring radio emission and about detecting planets around pulsars through precision timing. He also talked about Jupiter-Io like emission from compact planetary systems, and plans to search for such flaring events from low-mass stars, brown dwarfs, and white dwarfs. Read More

Team radar from across several institutions were busy this month observing many targets of interest, including Comet 46P/Wirtanen, near-Earth asteroid 2003 SD220, and 7 other NEAs. The cross-institution teams used the NASA-funded Arecibo S-band planetary radar to study these objects in order to measure their astrometry, size, and characterize their surfaces. Read More
