A complete census of planetary systems around a volume-limited sample of solar-type stars (FGK dwarfs) in the Solar neighborhood with uniform sensitivity down to Earth-mass planets within their Habita...
An aluminum/calcium-rich, iron-poor, white dwarf star: evidence for an extrasolar planetary lithosphere?

The presence of elements heavier than helium in white dwarf atmospheres is often a signpost for the existence of rocky objects that currently or previously orbited these stars. We have measured the ab...
OPTICAL SPECTRA OF RADIO PLANETARY NEBULAE IN THE SMALL MAGELLANIC CLOUD

We present preliminary results from spectral observations of four
(4) candidate radio sources co-identi¯ed with known planetary nebulae (PNe) in the
Small Magellanic Cloud (SMC). These were mad...
