Journal ArticleDOI
Differential Rotation and Dynamics of the Solar Interior
Michael Thompson,Juri Toomre,E. Anderson,H. M. Antia,Gabrielle Berthomieu,D. Burtonclay,S. M. Chitre,Joergen Christensen-Dalsgaard,Thierry Corbard,Marc L. DeRosa,Christopher R. Genovese,Douglas Gough,Deborah A. Haber,J. W. Harvey,Frank Hill,R. Howe,Sylvain G. Korzennik,Alexander G. Kosovichev,John Leibacher,Frank P. Pijpers,Janine Provost,Edward J. Rhodes,Jesper Schou,Takashi Sekii,Philip B. Stark,P. R. Wilson +25 more
TL;DR: Frequency splittings derived from GONG observations confirm that the variation of rotation rate with latitude seen at the surface carries through much of the convection zone, at the base of which is an adjustment layer leading to latitudinally independent rotation at greater depths.
Journal ArticleDOI
Evidence for Multiple Companions to υ Andromedae
R. Paul Butler,Geoffrey W. Marcy,Debra A. Fischer,Timothy M. Brown,Adam R. Contos,Sylvain G. Korzennik,Peter Nisenson,Robert W. Noyes +7 more
TL;DR: In this paper, a three-planar system was found to be dynamically stable by both analytic techniques and numerical simula- tions, with minimum masses of 2.83 and 2.5 AU.
Journal ArticleDOI
An Upper Limit on the Reflected Light from the Planet Orbiting the Star τ Bootis
David Charbonneau,Robert W. Noyes,Sylvain G. Korzennik,Peter Nisenson,Saurabh Jha,Steven S. Vogt,Robert I. Kibrick +6 more
TL;DR: In this article, it was shown that a planet orbiting a star at a separation of 0.046 AU could produce a reflected light flux as bright as 1 × 10-4 relative to that of the star.
Journal ArticleDOI
A Planet Orbiting the Star ρ Coronae Borealis
Robert W. Noyes,Saurabh Jha,Sylvain G. Korzennik,M. Krockenberger,Peter Nisenson,Timothy M. Brown,E. J. Kennelly,Scott D. Horner +7 more
TL;DR: In this paper, the radial velocity variations of the G0V star ρ CrB have been found to be consistent with the existence of an orbital companion in a circular orbit.
Journal ArticleDOI
New Observational Constraints on the υ Andromedae System with Data from the Hubble Space Telescope and Hobby-Eberly Telescope
Barbara McArthur,G. Fritz Benedict,Rory Barnes,Elder Martioli,Elder Martioli,Sylvain G. Korzennik,Ed Nelan,R. Paul Butler +7 more
TL;DR: In this paper, the authors used high-cadence radial velocity (RV) measurements from the Hobby-Eberly Telescope with existing velocities from the Lick, Elodie, Harlan J. Smith, and Whipple 60'' telescopes combined with astrometric data from the Hubble Space Telescope Fine Guidance Sensors to refine the orbital parameters and determine the orbital inclinations and position angles of the ascending node of components υ And A c and d.
