Results of stellar model fits to the out-of-transit stellar spectra. Top: flux-calibrated order 1 stellar spectra for the four LHS 1140 b visits and one LHS 1140 c are shown in colored points and the best-fitting NewEra stellar model in black. In gray is a NewEra model using the stellar parameters from C. Cadieux et al. (2024), which does not produce a satisfactory match to the data. Middle: model residuals from each of the five visits. Bottom: marginal posterior distributions for several key model parameters. The fits find consistent properties between the five visits, with evidence for both colder and warmer components in addition to the background photosphere. Note that 2300 K is the coldest model available in the NewEra grid.
