Multi-Scene Doppler Power Spectrum Modeling of LEO Satellite Channel Based on Atlas Fingerprint Method

open access: yesIEEE Access, 2021
The modeling of low earth orbit (LEO) satellite channel depends on its Doppler power spectrum. Due to satellite during transit, diversity and dynamic channel scene, the modeling of Doppler power spectrum has two serious problems: one is that the shape of

An Estimate of the Yield of Single-transit Planetary Events from the Transiting Exoplanet Survey Satellite [PDF]

open access: yesAstronomical Journal, 2018
We present a semianalytic estimate of the expected yield of single-transit planets from the Transiting Exoplanet Survey Satellite (TESS). We use the TESS Candidate Target List-6 (CTL-6) as an input catalog of over four million sources.

Revisiting the Transit Timing Variations in the TrES-3 and Qatar-1 Systems with TESS Data [PDF]

open access: yesAstronomical Journal, 2022
We present and analyze 58 transit light curves of TrES-3b and 98 transit light curves of Qatar-1b, observed by the Transiting Exoplanet Survey Satellite, plus two transit light curves of Qatar-1b, observed by us, using a ground-based 1.23 m telescope ...

Identifying Planetary Transit Candidates in TESS Full-frame Image Light Curves via Convolutional Neural Networks [PDF]

open access: yesAstronomical Journal, 2021
The Transiting Exoplanet Survey Satellite (TESS) mission measured light from stars in ∼75% of the sky throughout its 2 yr primary mission, resulting in millions of TESS 30-minute-cadence light curves to analyze in the search for transiting exoplanets. To

Transit detection of the long-period volatile-rich super-Earth ν2 Lupi d with CHEOPS [PDF]

open access: yesNature Astronomy, 2021
Exoplanets transiting bright nearby stars are key objects for advancing our knowledge of planetary formation and evolution. The wealth of photons from the host star gives detailed access to the atmospheric, interior and orbital properties of the ...
