Figure caption: Spectra and photometry of HIP 21152 B. The blue points are the SPHERE/IFS spectrum from Bonavita et al. (2022), the green diamonds are the SPHERE/IRDIS K 1 and K 2 photometry from Bonavita et al. (2022), the orange points are our new SCExAO/CHARIS spectrum, and the pink diamond is our Keck/NIRC2 ﹩L^{\prime} ﹩ photometry. Due to the modest discrepancy between the two reductions of the SPHERE/IFS spectrum at short wavelengths (Section 4.3.1), we exclude the λ < 1.15 μm region (shown in gray) from our analysis.

Figure caption: Near-infrared color–magnitude diagrams of HIP 21152 B. The companion’s position in each plot is denoted by the yellow star. The uncertainties on the companion’s magnitudes are smaller than the symbol size. The background points are L (red), T (blue), and Y (purple) dwarfs from The UltracoolSheet. The companion’s positions on these two CMDs are consistent with a late-L or early-T spectral type.

Figure caption: Comparison between the mass predictions of hot-start evolutionary models and the dynamical mass (top distribution) of HIP 21152 B. The median and 68.3% confidence interval are highlighted for each distribution. The dynamical mass is lower than most model predictions by 1–2σ. The hybrid Saumon & Marley (2008) grid is most consistent with the dynamical mass, agreeing to within 1.2σ.

Figure caption: Comparison of the SPHERE/IFS spectrum (red), CHARIS spectrum (blue), and SPHERE/IRDIS photometry (red) of HIP 21152 B to L4–T3 spectral standards. We find that the T0 spectrum provides the best match to the data. We thus assign a spectral type of T0±1 for the brown dwarf companion.

Figure caption: Age predictions from the luminosity and mass of HIP 21152 B for several hot-start evolutionary models. The median and 68.3% confidence interval are highlighted for each distribution. In general, the inferred ages are about 2σ lower than the age of the Hyades (650 ± 100 Myr).

Figure caption: Spectra and photometry of HIP 21152 B compared with the best-fit retrievals for each of the five prescriptions we consider. Here we show the retrievals performed with the complete data set (IFS and CHARIS spectra, and photometry) using Reduction 2 for the SPHERE/IFS spectrum. The colors of the spectra and photometry are the same as in Figures 3 and 12. The retrieval models have been smoothed to a resolving power of R = 25.

Figure caption: Top: proper motions of HIP 21152 A (blue) and HIP 21152 C (red) from Gaia EDR3 (top left) and PS1 (top right), overlaid with nearby sources within a radius of 1° (gray). We only show PS1 neighbors if their proper motions have S/N > 5 or have errors <10 mas yr−1. The host star does not have a PS1 proper motion given that it is saturated, so we plot its Gaia EDR3 proper motion (blue open symbol) in the top-right panel. Bottom: Gaia EDR3 proper motions and parallaxes of HIP 21152 AC and nearby sources shown in the top-left panel. The potential association between the A and C components is indicated by their common proper motions and parallaxes.

Figure caption: Reduced chi-square (﹩{\chi }_{\nu }^{2},﹩ left) and goodness-of-fit (G, right) values for model spectra from Saumon & Marley (2008) compared with HIP 21152 B’s spectra and photometry. Here, Reduction 1 is used for the SPHERE/IFS spectrum. The two metrics produce different best-fitting spectra. ﹩{\chi }_{\nu }^{2}﹩ yields a best-fit spectrum with T eff = 1500 K, ﹩\mathrm{log}g=4.5﹩, and f sed = 3, while G gives a best-fitting spectrum with T eff = 1400 K, ﹩\mathrm{log}g=4.5﹩, and f sed = 2.

Figure caption: Spectra and photometry of HIP 21152 B compared with the best-fitting Saumon & Marley (2008) model spectrum (black). The model represents T eff = 1400 K, ﹩\mathrm{log}g=4.5\,\mathrm{dex}﹩, and f sed = 2, and has been smoothed to a resolving power of R = 25. Reduction 2 is used for the SPHERE/IFS spectrum. The atmospheric model reproduces the companion’s spectra well, although we find a slight excess in ﹩L^{\prime} ﹩ that might hint at disequilibrium chemistry from 3 to 4 μm.

Figure caption: Comparison of best-fitting model spectra with HIP 21152 B’s spectra and photometry. The two curves show the best-fitting spectra based on ﹩{\chi }_{\nu }^{2}﹩ (light green) and G (blue). Here, Reduction 1 is used for the SPHERE/IFS spectrum. The model spectra have been smoothed to a resolving power of R = 25.

Figure caption: Spectra and photometry of HIP 21152 B compared with the best-fit retrievals from the five retrieval versions we consider. These retrievals incorporate all available data (IFS + CHARIS + Photometry) and adopt Reduction 1 for the SPHERE/IFS spectrum. The retrieved spectra are smoothed to a resolving power of R = 25.

Figure caption: Comparing the angular diameter fit using four-way data (top half) from 2005 with that of six-way data from 2021 (bottom half) for HD 187929/η Aql. The symbols are the same as in Figure 2, while bottom portion of each half shows the residuals to the angular diameter fit. The four-way data had three siderostats per spectrograph, while the six-way data had four siderostats per spectrograph, which partially accounts for the increased scatter in the residuals for the latter.
