T.; Regibo, S.; Royer, P.; Sicilia-Aguilar, A.; Swinyard, B. M.; Walker, H. J.; Wesson, R. (2010)

We obtained Herschel PACS and SPIRE images of the thermal emission of the debris disk around the A5V star beta Pic. The disk is well resolved in the PACS filters at 70, 100, and 160 mu m. The surface brightness profiles ...

Limits On Planets Around Pulsating White Dwarf Stars

Mullally, Fergal; Winget, D. E.; Degennaro, Steven; Jeffery, Elizabeth; Thompson, Susan E.; Chandler, Dean; Kepler, S. O. (2008-03)

We present limits on planetary companions to pulsating white dwarf stars. A subset of these stars exhibit extreme stability in the period and phase of some of their pulsation modes; a planet can be detected around such a ...

A Second Giant Planet In 3:2 Mean-Motion Resonance In The HD 204313 System

Robertson, Paul; Horner, Jonathan; Wittenmyer, Robert A.; Endl, Michael; Cochran, William D.; MacQueen, Phillip J.; Brugamyer, Erik J.; Simon, Attila E.; Barnes, Stuart I.; Caldwell, Caroline (2012-07)

We present eight years of high-precision radial velocity (RV) data for HD 204313 from the 2.7 m Harlan J. Smith Telescope at McDonald Observatory. The star is known to have a giant planet (M sin i = 3.5 M-J) on a similar ...

The Pan-Pacific Planet Search. II. Confirmation Of A Two-Planet System Around Hd 121056

Wittenmyer, Robert A.; Wang, Lifan; Liu, Fan; Horner, Jonathan; Endl, Michael; Johnson, John A.; Tinney, C. G.; Carter, B. D. (2015-02)

Precise radial velocities from the Anglo-Australian Telescope (AAT) confirm the presence of a rare short-period planet around the K0 giant HD 121056. An independent two-planet solution using the AAT data shows that the ...

The Solar Twin Planet Search I. Fundamental Parameters Of The Stellar Sample

Ramirez, I.; Melendez, J.; Bean, J.; Asplund, M.; Bedell, M.; Monroe, T.; Casagrande, L.; Schirbel, L.; Dreizler, S.; Teske, J.; Maia, M. T.; Alves-Brito, A.; Baumann, P. (2014-12)

Context. We are carrying out a search for planets around a sample of solar twin stars using the HARPS spectrograph. The goal of this project is to exploit the advantage offered by solar twins to obtain chemical abundances ...
