An Independent Planet Search In The Kepler Dataset. II. An extremely low-density super-Earth mass planet around Kepler-87
Aviv Ofir, Stefan Dreizler, Mathias Zechmeister +1
[ABRIDGED]: Aims: two candidates in the KOI 1574 system are relatively long-period (about 114d and 191d) and in 5:3 resonance. We therefore search for TTVs in this particularly pro…
Position angles and coplanarity of multiple systems from transit timing
Aviv Ofir
Aims: We compare the apparent difference in timing of transiting planets (or eclipsing binaries) that are observed from widely separated locations (parallactic delay). Methods: A s…
KeSeF - Kepler Self Follow-up Mission
Aviv Ofir
The Kepler spacecraft is currently unable to hold a steady pointing and it is slowly drifting during observations. We believe that if one has to deal with targets that drift across…
Optimizing the search for transiting planets in long time series
Aviv Ofir
Context: Transit surveys, both ground- and space- based, have already accumulated a large number of light curves that span several years. Aims: The search for transiting planets in…
Kepler-77b: a very low albedo, Saturn-mass transiting planet around a metal-rich solar-like star
D. Gandolfi, H. Parviainen, M. Fridlund +18
We report the discovery of Kepler-77b (alias KOI-127.01), a Saturn-mass transiting planet in a 3.6-day orbit around a metal-rich solar-like star. We combined the publicly available…
