Stellar Proper Motions in the Galactic Bulge from deep HST ACS/WFC Photometry (2008)

Clarkson, Will, Sahu, Kailash, Anderson, Jay, Smith, T. Ed., Brown, Thomas M., Rich, R. Michael, ...

We present stellar proper motions in the Galactic bulge from the Sagittarius Window Eclipsing Extrasolar Search (SWEEPS) project using ACS/WFC on HST. Proper motions are extracted for more than...

Planets in the Galactic Bulge: Results from the SWEEPS Project (2007)

Sahu, Kailash C., Casertano, Stefano, Valenti, Jeff, Bond, Howard E., Brown, Thomas M., Smith, T. Ed, ...

The exoplanets discovered so far have been mostly around relatively nearby and bright stars. As a result, the host stars are mostly (i) in the Galactic disk, (ii) relatively massive, and (iii)...

Gaseous Inner Disks (2007)

Najita, Joan R., Carr, John S., Glassgold, Alfred E., Valenti, Jeff

As the likely birthplaces of planets and an essential conduit for the buildup of stellar masses, inner disks are of fundamental interest in star and planet formation. Studies of the gaseous component...

Transiting extrasolar planetary candidates in the Galactic bulge (2006)

Sahu, Kailash C., Casertano, Stefano, Bond, Howard E., Valenti, Jeff, Smith, T. Ed, Minniti, Dante, ...

More than 200 extrasolar planets have been discovered around relatively nearby stars, primarily through the Doppler line shifts owing to the reflex motions of their host stars, and more recently...

The First Extrasolar Planet Discovered with a New Generation High Throughput Doppler Instrument (2006)

Ge, Jian, Van Eyken, Julian, Mahadevan, Suvrath, DeWitt, Curtis, Kane, Stephen R., Cohen, Roger, ...

We report the detection of the first extrasolar planet, ET-1 (HD 102195b), using the Exoplanet Tracker (ET), a new generation Doppler instrument. The planet orbits HD 102195, a young star with solar...

THE FIRST EXTRASOLAR PLANET DISCOVERED WITH A NEW-GENERATION HIGH-THROUGHPUT DOPPLER INSTRUMENT (2006)

Jian Ge, Julian Van Eyken, Suvrath Mahadevan, Curtis Dewitt, Stephen R. Kane, Roger Cohen, ...

We report the detection of the first extrasolar planet, ET-1 (HD 102195b), using the Exoplanet Tracker (ET), a new-generation Doppler instrument. The planet orbits HD 102195, a young star with solar...

HST/STIS High Resolution Echelle Spectra of alpha Centauri A (G2 V) (2003)

Pagano, Isabella, Linsky, Jeffrey L., Valenti, Jeff, Duncan, Douglas K.

We describe and analyze HST/STIS observations of the G2 V star alpha Centauri A (alpha Cen A, HD 128620), a star similar to the Sun. The high resolution echelle spectra obtained with the E140H and...

The Phoenix Spectrograph at Gemini South (2003)

Kenneth Hinkle Robert, Robert Blum, Richard R. Joyce, Steven T. Ridgway, Bernadette Rodgers, Nigel Sharp, ...

Phoenix, a high resolution near-infrared spectrograph build by NOAO, was first used on the Gemini South telescope in December 2001. Previously on the Kitt Peak 2.1 and 4 meter telescopes, Phoenix...
