Shape and spin state model of contact binary (388188) 2006 DP14 using combined radar and optical observations
Richard E. Cannon, Agata Rozek, Marina Brozović +36
Contact binaries are found throughout the solar system. The recent discovery of Selam, the satellite of MBA (152830) Dinkinesh, by the NASA LUCY mission has made it clear that the…
OGLE-2015-BLG-1609Lb: Sub-jovian planet orbiting a low-mass stellar or brown dwarf host
M. J. Mróz, R. Poleski, A. Udalski +70
We present a comprehensive analysis of a planetary microlensing event OGLE-2015-BLG-1609. The planetary anomaly was detected by two survey telescopes, OGLE and MOA. Each of these s…
