A search for technosignatures from TRAPPIST-1, LHS 1140, and 10 planetary systems in the Kepler field with the Green Bank Telescope at 1.15-1.73 GHz
Abstract
As part of our ongoing search for technosignatures, we collected over three terabytes of radio astronomy data in May 2017 using the L-band receiver (1.15-1.73 GHz) of the 100 m diameter Green Bank Telescope (GBT). These observations focused primarily on planetary systems in the Kepler field, but also included scans of the recently discovered TRAPPIST-1 and LHS 1140 systems. We will present the results of our search for narrowband signals in this data set with techniques that are generally similar to those described by Margot et al. (2018, https://arxiv.org/abs/1802.01081). We will also describe several improvements to our search algorithms that make the identification of radio-frequency interference (RFI) more robust. In particular, we describe improvements to the characterization of signals that we resolve in the frequency domain.
