Evolutionary models for solar metallicity low-mass stars: mass-magnitude relationships and color-magnitude diagrams
read the original abstract
We present evolutionary models for low mass stars from 0.075 to 1 $\msol$ for solar-type metallicities [M/H]= 0 and -0.5. The calculations include the most recent interior physics and the latest generation of non-grey atmosphere models. We provide mass-age-color-magnitude relationships for both metallicities. The mass-M$_V$ and mass-M$_K$ relations are in excellent agreement with the empirical relations derived observationally. The theoretical color-magnitude diagrams are compared with the sequences of globular clusters (47 Tucanae) and open clusters (NGC2420 and NGC2477) observed with the Hubble Space Telescope. Comparison is also made with field star sequences in $M_V$-$(V-I)$, $M_K$-$(I-K)$ and $M_K$-$(J-K)$ diagrams. These comparisons show that the most recent improvements performed in low-mass star atmosphere models yield now reliable stellar models in the near-infrared. These models can be used for metallicity, mass, temperature and luminosity calibrations. Uncertainties still remain, however, in the optical spectral region below $T_{eff} \sim 3700K$, where predicted (V-I) colors are too blue by 0.5 mag for a given magnitude. The possible origins for such a discrepancy, most likely a missing source of opacity in the optical and the onset of grain formation are examined in detail.

Ultraviolet Imaging of SR 12 c with HST/WFC3: Accretion and Variability of a Giant Planet at the End Stages of Growth
HST/WFC3 UV imaging of SR 12 c measures accretion luminosity of 1.65 ± 0.19 × 10^{-5} L_⊙ and rate of 8 ± 2 × 10^{-12} M_⊙ yr^{-1}, placing it at the end stages of giant planet assembly with a full UV-to-sub-mm SED.

JWST's Constraints on the Substellar IMF in NGC 2024
JWST NIRSpec spectroscopy of NGC 2024 members yields no evidence for a substellar IMF turnover below 12 Mjup, contrary to a prior photometric-only claim.

Statistics on the population of distant substellar companions to nearby stars
Wide substellar companions around nearby stars follow power-law mass and separation distributions consistent with stellar binaries, with an occurrence rate of about 1% at 1,000–20,000 AU.

TESS light curves and surface activity in two low-mass eclipsing binaries: NSVS 01031772 and 2MASS J04100497+2931023
TESS and ground-based photometry of two low-mass eclipsing binaries yield improved stellar parameters, evidence for tertiary companions via the light-time effect, and a flare frequency of one per 40 hours for NSVS 01031772.

Analysis of the young disk around WRAY 15-1880: does it contain a primitive planetary system?
A candidate 0.3-7.6 MJup companion is reported in the gap of the ~2.8 Myr pre-transitional disk around WRAY 15-1880, with an ALMA blob interpreted as a vortex at the m=1 Lindblad resonance.

The Cohesive Object Sequence: The Mass-Density Distribution of Astronomical Objects from Asteroids to Stars
Astronomical objects from asteroids to stars mostly follow a cohesive mass-density sequence reflecting gravitational contraction and nuclear ignition, while compact stellar remnants deviate from it.
