Synthetic activity indicators for M-type dwarf stars [PDF]
Proceedings of the International Astronomical Union, 2015 AbstractHere, we present a set of time-dependent 3D RMHD simulations of a M-dwarf star representative of AD Leo, which extend from the upper convection zone into the chromosphere. The 3D model atmospheres are characterized by a very dynamic and intermittent structure on small spatial and temporal scales and a wealth of physical processes, which by ...

Advanced Optical Materials, EarlyView.Cellulose nanocrystals (CNCs) self‐assemble in aqueous suspension into chiral nematic liquid crystals, resulting in structurally colored films upon drying. Here, the influence of sugar additives on CNC self‐assembly in suspension and in films are studied.

Precise Mass, Orbital Motion, and Stellar Properties of the M-dwarf Binary LP 349−25AB
The Astrophysical JournalLP 349−25 is a well-studied close stellar binary system comprised of two late M dwarf stars, where both stars are close to the limit between star and brown dwarf. This system was previously identified as a source of gigahertz radio emission.

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 ...

Electronic Nose for Indoor Mold Detection and Identification
Advanced Sensor Research, EarlyView.This study explores the potential of a SnO2 nanowire‐based chemiresistive electronic nose not only to detect but also to identify two common indoor mold species, Stachybotrys chartarum and Chaetomium globosum on two different growth substrates. In a laboratory setup, the electronic nose displays high classification performance using optimized linear ...

The Comprehensive Archive of Substellar and Planetary Accretion Rates
The Astronomical Journal, 2023 Accretion rates ( $\dot{M}$ ) of young stars show a strong correlation with object mass ( M ); however, extension of the $\dot{M}\mbox{--}M$ relation into the substellar regime is less certain. Here, we present the Comprehensive Archive of Substellar and

The theoretical instability strip of M dwarf stars [PDF]
Monthly Notices of the Royal Astronomical Society, 2013 The overstability of the fundamental radial mode in M dwarf models was theoretically predicted by Rodr guez-L pez et al. (2012). The periods were found to be in the ranges ~25-40 min and ~4-8 h, depending on stellar age and excitation mechanism. We have extended our initial M dwarf model grid in mass, metallicity, and mixing length parameter. We have
