Kinematics of Molecular Hydrogen Emission from Pre-planetary Nebulae: RAFGL 2688 and RAFGL 618

Joel H. Kastner, David A. Weintraub, Ian Gatley +1

We present high spectral resolution maps of near-infrared molecular hydrogen emission from the bipolar pre-planetary nebulae RAFGL 2688 and RAFGL 618, obtained with the NOAO Phoeni…

The ages of very cool hydrogen-rich white dwarfs

M. Salaris, E. Garcia-Berro, M. Hernanz +2

The evolution of white dwarfs is essentially a cooling process that depends primarily on the energy stored in their degenerate cores and on the transparency of their envelopes. In…

Cooling sequences and color-magnitude diagrams for cool white dwarfs with hydrogen-atmospheres

Gilles Chabrier, Pierre Brassard, Gilles Fontaine +1

We present new cooling sequences, color-magnitude diagrams, and color-color diagrams for cool white dwarfs with pure hydrogen atmospheres down to an effective temperature $\te=1500…

Molecular Abundances in the Atmosphere of the T Dwarf Gl 229B

D. Saumon, T. R. Geballe, S. K. Leggett +5

We present new, high resolution, infrared spectra of the T dwarf Gliese 229B in the J, H, and K bandpasses. We analyze each of these as well as previously published spectra to dete…

On the Radii of Close-in Giant Planets

A. Burrows, T. Guillot, W. B. Hubbard +4

The recent discovery that the close-in extrasolar giant planet, HD209458b, transits its star has provided a first-of-its-kind measurement of the planet's radius and mass. In additi…

Pinpointing the Position of the Post-AGB Star at the Core of RAFGL 2688 using Polarimetric Imaging with NICMOS

David A. Weintraub, Joel H. Kastner, Dean C. Hines +1

We have used infrared polarimetric imaging with NICMOS to determine precisely the position of the star that illuminates (and presumably generated) the bipolar, pre-planetary reflec…

NICMOS Narrow-band Infrared Photometry of TW Hya Association Stars

David A. Weintraub, Didier Saumon, Joel H. Kastner +1

We have obtained 1.64, 1.90 and 2.15 micron narrow-band images of five T Tauri stars in the TW Hya Association (TWA) using the Near-Infrared Camera and Multiobject Spectrometer abo…

Signatures for a Cosmic Flux of Magnetic Monopoles

Stuart D. Wick, Thomas W. Kephart, Thomas J. Weiler +1

Any early universe phase transition occurring after inflation has the potential to populate the universe with relic magnetic monopoles. Observations of galactic magnetic fields, as…
