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…
The EREBOS project -- Investigating the effect of substellar and low-mass stellar companions on late stellar evolution
V. Schaffenroth, B. N. Barlow, S. Geier +14
Eclipsing post-common envelope binaries are highly important for resolving the poorly understood, very short-lived common envelope phase. Most hot subdwarfs (sdO/Bs) are the bare H…
Kepler Object of Interest Network III. Kepler-82f: A new non-transiting $21 M_\bigoplus$ planet from photodynamical modelling
J. Freudenthal, C. von Essen, A. Ofir +13
Context. The Kepler Object of Interest Network (KOINet) is a multi-site network of telescopes around the globe organised for follow-up observations of transiting planet candidate K…
Indications for transit timing variations in the exo-Neptune HAT-P-26b
C. von Essen, S. Wedemeyer, M. S. Sosa +8
From its discovery, the low density transiting Neptune HAT-P-26b showed a 2.1-sigma detection drift in its spectroscopic data, while photometric data showed a weak curvature in the…
First Light of Engineered Diffusers at the Nordic Optical Telescope Reveal Time Variability in the Optical Eclipse Depth of WASP-12b
C. von Essen, G. Stefansson, M. Mallonn +6
We present the characterization of two engineered diffusers mounted on the 2.5 meter Nordic Optical Telescope, located at Roque de Los Muchachos, Spain. To assess the reliability a…
The OmegaWhite survey for short-period variable stars - V. Discovery of an ultracompact hot subdwarf binary with a compact companion in a 44 minute orbit
T. Kupfer, G. Ramsay, J. van Roestel +20
We report the discovery of the ultracompact hot subdwarf (sdOB) binary OW J074106.0-294811.0 with an orbital period of P min, making it the…
