AAVSO Alert Notice 566: Beta Pic observations requested for BRITE-Constellation
Active Dates: Jan. 31, 2017 – Dec. 31, 2018
Abstract:
The BRIght Target Explorer-Constellation (BRITE-Constellation) satellite suite is obtaining high-precision photometry of selected very bright (mv < 4) stars. Its purpose is to investigate the "stellar structure and evolution of the brightest stars in the sky and their interaction with the local environment." The AAVSO is part of the BRITE-Constellation Ground Based Observations Team (GBOT), supporting cutting-edge science from the BRITE-Constellation satellites and coordinating with BRITE-Constellation scientist Dr. Konstanze Zwintz (Universitaet Innsbruck) and her team.
Justification:
The delta Scuti star beta Pic (NSV 16683) (3.80-3.86V) is one of the BRITE stars being focused on during this season. Bet Pic is particularly interesting now because a transit of the star's planet's Hill sphere is predicted to occur during 2017-2018. Ongoing observations beginning now are valuable to establish a baseline prior to the transit.
