Roberto Silvotti,Sonja Schuh,Rimvydas Janulis,J. E. Solheim,S. Bernabei,Roy Ostensen,Terry D. Oswalt,I Bruni,R Gualandi,Alfio Bonanno,G. Vauclair,Michael D. Reed,C. W. Chen,Elia M. Leibowitz,M. Paparó,Andrzej S. Baran,Stéphane Charpinet,N. Dolez,S. D. Kawaler,D. W. Kurtz,Pawel Moskalik,Reed Riddle,Staszek Zola,Staszek Zola +23 more
TL;DR: The detection of a planet orbiting a post-red-giant star demonstrates that planets with orbital distances of less than 2 au can survive the red-Giant expansion of their parent stars.
Journal ArticleDOI
A compact system of small planets around a former red-giant star
Stéphane Charpinet,Gilles Fontaine,Pierre Brassard,Elizabeth M. Green,Valérie Van Grootel,Suzanna K. Randall,Roberto Silvotti,Andrzej S. Baran,Roy Ostensen,S. D. Kawaler,J. H. Telting +10 more
TL;DR: The presence of two nearly Earth-sized bodies orbiting the post-red-giant, hot B subdwarf star KIC 05807616 is reported, which may be the dense cores of evaporated giant planets that were transported closer to the star during the engulfment and triggered the mass loss necessary for the formation of the hot B subswarf.
Journal ArticleDOI

TL;DR: In this paper, the authors present results from the final 6 months of a survey to search for pulsations in white dwarfs (WDs) and hot subdwarf stars with the Kepler spacecraft.
Journal ArticleDOI
Three ways to solve the orbit of KIC11558725: a 10 day beaming sdB+WD binary with a pulsating subdwarf
J. H. Telting,R. H. Østensen,Andrzej S. Baran,Steven Bloemen,Michael D. Reed,R. Oreiro,L. Farris,T. A. Ottosen,Conny Aerts,Steven D. Kawaler,U. Heber,S. Prins,E. M. Green,Belinda Kalomeni,Simon J. O'Toole,Fergal Mullally,D. T. Sanderfer,Jeffrey C. Smith,H. Kjeldsen +18 more
TL;DR: In this article, the authors obtained ground-based spectroscopic Balmer-line radial-velocity measurements of KIC11558725, spanning the 2010 and 2011 observing seasons.

TL;DR: In this article, the authors obtained ground-based spectroscopic radial-velocity measurements of KIC 11558725 based on low-resolution spectra in the Balmer line region, spanning the 2010 and 2011 observing seasons.
