LHS 3154 Archives

EWs for the K i lines in the J band vs. NIR spectral type for M dwarfs in our sample. The figure elements are the same as in Figure 3. The panels display: (a) NIR spectral type vs. K i 1.169 µm EW, (b) NIR spectral type vs. K i 1.177 µm EW, and (c) NIR spectral type vs. K i 1.253 µm EW. -- astro-ph.EP

Gravity-sensitive Spectral Indices In Ultracool Dwarfs: Investigating Correlations With Metallicity And Planet Occurrence Using SpeX and FIRE Observations

by Keith CowingJune 30, 2025June 28, 2025

We present a near-infrared spectroscopic analysis (0.9-2.4 micron) of gravity indices for 57 ultracool dwarfs (spectral types M5.5 to L0), including exoplanet hosts TRAPPIST-1, SPECULOOS-2, SPECULOOS-3, and LHS 3154. Our […]
