Abstract: The timing method, using either stellar pulsations or eclipse timing of close binaries as a clock, is proving to be an efficient way to detect planets around stars that have evolved beyond the red giant branch. In this article we present a short review of the recent discoveries and we investigate the potential of the timing method using data both from ground‐based facilities as well as from the Kepler and CoRoT space missions.

The search for substellar companions to subdwarf B stars in connection with evolutionary aspects
Ronny Bernd Lutz
- 14 Dec 2011
TL;DR: In this article, the authors investigated two pulsating subdwarf B stars with the goal to search for substellar companions and to directly measure the evolutionary timescales of these stars.

Pulsating stars harbouring planets
TL;DR: A review of past and current research in exoplanet asteroseismology and guidelines for the future is given in this paper. But, as stated in the review, "the synergy between the two fields opens up new aspects in both fields and allows the possibility of discovering new exoplanets through time delay studies".

Foretellings of Ragnarök: World-engulfing Asymptotic Giants and the Inheritance of White Dwarfs
TL;DR: In this paper, the authors studied the evolution of planets while following each thermal pulse on the asymptotic giant branch (AGB) and found the closest radii at which planets will be found around white dwarfs, assuming that any planet entering the stellar envelope is destroyed.

TL;DR: In this article, the authors used published, reanalysed, and new mid-eclipse times of the white dwarf in DP\,Leo, obtained between 1979 and 2010, to find agreement with the light-travel-time effect produced by a third body in an elliptical orbit.

TL;DR: In this article, a close substellar companion has been claimed to orbit the bright sdB star HD 149382 with a period of 2.391 d. In order to check this important discovery, they gathered 26 high resolution spectra over 55 days with the HERMES spectrograph on the 1.2 m Mercator telescope on La Palma, and analyzed the resulting radial velocities.

TL;DR: In this paper, two circumbinary planets were detected around the close binary system NN Serpentis using the orbital time delay effect measured via the sharp eclipses of the white dwarf primary.

TL;DR: In this paper, the authors reported the detection of a planetary companion around HIP 13044, a metal-poor star on the red Horizontal Branch. The detection is based on radial velocity observations with FEROS, a high-resolution spectrograph at the ESO La Silla observatory in Chile.
