No Evidence for More Earth-sized Planets in the Habitable Zone of Kepler's M versus FGK Stars
The Astronomical Journal, 2023 Reliable detections of Earth-sized planets in the habitable zone remain elusive in the Kepler sample, even for M dwarfs. The Kepler sample was once thought to contain a considerable number of M-dwarf stars ( T _eff < 4000 K), which hosted enough Earth ...

The Vegan Villain Sets Out to The End of Summer: Functionalized Coatings as Biohybrid UV‐Sensors
Advanced Materials Interfaces, EarlyView.This study introduces biohybrid coatings incorporating E. coli biomass expressing photoconvertible fluorescent proteins as UV‐A responsive elements. Upon irradiation at 400 nm, the coatings exhibit an irreversible fluorescence shift from green to red within 15 min. Notably, the photoconversion capability is retained after >1 year of storage.

Stellar model chromospheres. XIII - M dwarf stars
The Astrophysical Journal, 1982 Single-component, homogeneous model chromospheres that are consistent with high-resolution profiles of the Ca II K line calibrated in surface flux units for three dMe and 2 dM stars observed at quiescent times are constructed. The models reveal several systematic trends.

Pattern Formation in Non‐Equilibrium Architected Materials
Advanced Materials Technologies, EarlyView.This article demonstrates an artificial mechanical system ‐ a robotic metamaterial ‐ as an accessible and versatile platform within which to explore and prescribe the reaction‐diffusion driven pattern formation hitherto associated with comparatively less accessible and versatile non‐equilibrium biological and chemical systems.

Stellar Atmospheric Parameters for Cool Dwarfs in Gaia Data Release 3
The Astrophysical Journal Supplement SeriesWe provide a catalog of atmospheric parameters for 1,806,921 cool dwarfs from Gaia Data Release 3 (DR3) that lie within the range covered by LAMOST cool dwarf spectroscopic parameters: 3200 K < T _eff < 4300 K, −0.8 < [M/H] < 0.2 dex, and 4.5 < log g < 5.

Radio burst statistics for M dwarf flare stars [PDF]
Astronomy and Astrophysics Supplement Series, 1997 We present a critical analysis on the number of bursts near 21 cm from nine dMe flare stars of the solar neighborhood as reported in the literature. We compare our findings with the number of bursts detected with the Arecibo radiotelescope between 1989 and 1993, using a very reliable method to discriminate between stellar and artificial emissions.

The Future of Research in Cognitive Robotics: Foundation Models or Developmental Cognitive Models?
Advanced Robotics Research, EarlyView.Research in cognitive robotics founded on principles of developmental psychology and enactive cognitive science would yield what we seek in autonomous robots: the ability to perceive its environment, learn from experience, anticipate the outcome of events, act to pursue goals, and adapt to changing circumstances without resorting to training with ...

The Orbital Eccentricity–Radius Relation for Planets Orbiting M Dwarfs
The Astronomical JournalThe orbital eccentricity–radius relation for small planets is indicative of the predominant dynamical sculpting processes during late-stage orbital evolution. Previous studies have shown that planets orbiting Sun-like stars exhibit an eccentricity–radius
