SOPHIE and TESS characterization of fourteen TESS Objects of Interest: nine planetary systems and five low-mass stellar companions
N. Heidari, G. Hébrard, S. Sousa +61
We present fourteen TESS Objects of Interest (TOIs) from the SOPHIE-TESS follow-up program. Combining TESS photometry, SOPHIE radial velocities (RVs), ground-based photometry, and…
A Paradigm Shift in Exoplanet False Positive Identification with HIP-44302
Arielle C. Frommer, Jason D. Eastman, David R. Ciardi +5
Through detailed modeling of all three stars, we show that HIP-44302 is a false positive triple-star system. While the Transiting Exoplanet Survey Satellite initially designated th…
Characterization of seven transiting systems including four warm Jupiters from SOPHIE and TESS
N. Heidari, G. H'ebrard, E. Martioli +65
We present the study of seven systems, three of which TOI-2295, TOI-2537, and TOI-5110 are newly discovered planetary systems. Through the analysis of TESS photometry, SOPHIE radia…
