On July 31, 1999 the Lunar Prospector (LP) spacecraft was commanded to deorbit and thus impact into the floor of a permanently shadowed crater at -88.7S, 42E (Goldstein, et al. 1999, GRL 26, pp1653-1656 and paper 38.06 at this conference). Coordinated observational program (spectroscopy and imaging) were carried out at HST, SWAS, Keck, McDonald

The number of ultra-diffuse galaxies (UDGs) in clusters is of significant importance to constrain models of their formation and evolution. Furthermore, their distribution inside clusters may tell us something about their interactions with their environments. In this work, we revisit the abundance of UDGs in a more consistent way than in previous

We present Roche tomograms of the G5-G8 IV/V secondary star in the long-period cataclysmic variable BV Cen reconstructed from Magellan Inamori Kyocera Echelle spectrograph echelle data taken on the Magellan Clay 6.5-m telescope. The tomograms show the presence of a number of large, cool star-spots on BV Cen for the first time. In particular, we

The influence of the orientation angles of the target nucleus symmetry axis, relative to the beam direction, on the production of the evaporation residues is investigated for the 48Ca+154Sm reaction as a function of beam energy. At low energies (Ec.m. 180 MeV, σER ranges approximately 0.1-10 mb because the fission barrier for a compound nucleus

Kepler ultra-high precision photometry of long and continuous observations provides a unique dataset in which surface rotation and variability can be studied for thousands of stars. Because many of these old field stars also have independently measured asteroseismic ages, measurements of rotation and activity are particularly interesting in the
