Аннотация
Continuous data releases throughout the TESS primary mission will provide
unique opportunities for the exoplanet community at large to contribute to
maximizing TESS's scientific return via the discovery and validation of
transiting planets. This paper introduces our independent detection pipeline of
periodic transit events along with the results of its inaugural application to
the recently released 2 minute light curves of low mass stars from the first
two TESS sectors. The stellar parameters within our sample are refined using
precise parallax measurements from the GAIA DR2 which reduces the number of low
mass stars in our sample relative to those listed in the TESS Input Catalog. In
lieu of the follow-up observations required to confirm or refute the planetary
nature of transit-like signals, a validation of transit-like events flagged by
our pipeline is performed statistically. The resulting vetted catalog contains
seven probable blended eclipsing binaries, eight known TOIs, plus eight new
planet candidates smaller than 4 Earth radii. This work demonstrates the
ability of our pipeline to detect sub-Neptune-sized planet candidates which
to-date, represent some of the most attractive targets for future atmospheric
characterization via transmission or thermal emission spectroscopy and for
radial velocity efforts aimed at the completion of the TESS level one
requirement to deliver 50 planets smaller than 4 Earth radii with measured
masses.
