Pandora: A fast open-source exomoon transit detection algorithm

Transit Timing Effects due to an Exomoon

As the number of known exoplanets continues to grow, the question as to whether such bodies harbour satellite systems has become one of increasing interest. In this paper, we explore the transit timing effects that should be detectable due to an exomoon and predict a new observable. We first consider transit time variation (TTV), where we update the model to include the effects of orbital eccen...

Transit timing effects due to an exomoon II

In our previous paper, we evaluated the transit duration variation (TDV) effect for a co-aligned planet-moon system at an orbital inclination of i = 90◦. Here, we will consider the effect for the more general case of i 6 90◦ and an exomoon inclined from the planet-star plane by Euler rotation angles α, β and γ. We find that the TDV signal has two major components, one due to the velocity variat...

A fast semi-blind source separation algorithm

Many algorithms have been invented to perform blind source separation. There, it is assumed that the sources are completely unknown. However, in many cases of time series separation there exists some a priori knowledge on the behaviour of the sources. This is the case especially, when the data is collected in a controlled experiment. In this paper we introduce a fast semi-blind source separatio...

The BAST algorithm for transit detection

Context. The pioneer space mission for photometric exoplanet searches, CoRoT, steadily monitors about 12000 stars in each of its fields of view. Transit detection algorithms are applied to derive promising planetary candidates, which are then followed-up with ground-based observations. Aims. We present BAST (Berlin Automatic Search for Transits), a new algorithm for periodic transit detection, ...
