Pandora: A fast open-source exomoon transit detection algorithm
Michael Hippke, René Heller
We present Pandora, a new software to model, detect, and characterize transits of extrasolar planets with moons in stellar photometric time series. Pandora uses an analytical descr…
Signal preservation of exomoon transits during light curve folding
René Heller, Michael Hippke
In the search for moons around extrasolar planets, astronomers are confronted with a stunning observation. Although 3400 of the 4500 exoplanets were discovered with the transit met…
Spin Change of Asteroid 2012 TC4 probably by Radiation Torques
Hee-Jae Lee, Josef Ďurech, David Vokrouhlický +9
Asteroid 2012 TC4 is a small (10 m) near-Earth object that was observed during its Earth close approaches in 2012 and 2017. Earlier analyses of light curves revealed its exci…
Transit least-squares survey -- III. A transit candidate in the habitable zone of Kepler-160 and a nontransiting planet characterized by transit-timing variations
René Heller, Michael Hippke, Jantje Freudenthal +3
The Sun-like star Kepler-160 (KOI-456) has been known to host two transiting planets, Kepler-160 b and c, of which planet c shows substantial transit-timing variations (TTVs). We u…
Transit least-squares survey - I. Discovery and validation of an Earth-sized planet in the four-planet system K2-32 near the 1:2:5:7 resonance
René Heller, Kai Rodenbeck, Michael Hippke
We apply, for the first time, the Transit Least Squares (TLS) algorithm to search for new transiting exoplanets. TLS is a successor to the Box Least Squares (BLS) algorithm, which…
Transit least-squares survey -- II. Discovery and validation of 17 new sub- to super-Earth-sized planets in multi-planet systems from K2
René Heller, Michael Hippke, Kai Rodenbeck
The extended Kepler mission (K2) has revealed more than 500 transiting planets in roughly 500,000 stellar light curves. All of these were found either with the box least-squares al…
