tpfplotter target pixel file (TPF) image of TOI-406 as in Sector 3. The red squares correspond to the TESS aperture used to compute the photometry, the size of the red circles represent the Gaia DR3 (Gaia Collaboration et al. 2023) magnitudes of the stars. TOI-406 is positioned at the center (star 1). Star 2 is a G = 16.887 mag star which contribution to the aperture flux was taken into account by the SPOC pipeline by calculating the crowding metric and subtracting the corresponding percentage (< 0.14 percent in all four sectors) of the median flux level to account for dilution. The TPF of all sectors are shown in Appendix A. -- astro-ph.EP

Characterisation of TOI-406 as Showcase of the THIRSTEE program: A 2-Planet System Straddling the M-dwarf Density Gap

by Keith CowingSeptember 19, 2024November 16, 2024

The exoplanet sub-Neptune population currently poses a conundrum. Are small-size planets volatile-rich cores without atmosphere, or are they rocky cores surrounded by H-He envelope? To test the different hypotheses from […]
