The Peter Wehinger Fellowship Fund

Steward Astronomer Peter Wehinger passed away on April 27. Peter was passionately concerned about raising scholarship funds for both undergrads and graduate students, and did so successfully before his 2012 retirement. Therefore, his family and friends have set up a Peter Wehinger Fellowship Fund at the UA Foundation.  This fellowship will be used to recognize graduate students in the Dept of Astronomy with demonstrated records of exceptional or creative work.  A longer article about Peter and the fund can be found HERE. A direct link to the appropriate Foundation site, for donations, can be found HERE.

New AO Coronagraph Makes It Possible to See Planets Closer To Stars

Steward Observatory's MagAO team, and collaborators from Leiden University in the Netherlands, have just demonstrated a breakthrough in the quest to image extrasolar planets. Using a technique first proposed by Steward's John Codona, the new coronagraphs in MagAO's Clio infrared camera reach an extreme level of sensitivity to planets very close to their stars. These "Vector Apodizing Phase Plates" fold the light from a star out of the way, allowing the light from the...
