A spectral differential characterization of low-mass companions
EPJ Web of Conferences, 2013 We present a new approach with which the dynamical mass of low-mass companions around cool stars can be found. In order to discover companions to late-type stars the stellar spectrum is removed.

Infrared Mn i laboratory oscillator strengths for the study of late type stars and ultracool dwarfs [PDF]
Astronomy & Astrophysics, 2010 Aims. The aim of our new laboratory measurements is to measure accurate absolute oscillator strengths for neutral manganese transitions in the infrared needed for the study of late-type stars and ultracool dwarfs. Methods. Branching fractions have been measured by high resolution Fourier transform spectroscopy and combined with radiative level ...

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 ...

X-Ray, UV, and Optical Observations of Proxima Centauri’s Stellar Cycle
The Astrophysical JournalProxima Cen (GJ 551; dM5.5e) is one of only about a dozen fully convective stars known to have a stellar cycle, and the only one to have long-term X-ray monitoring.

The EUVE Optical Identification Campaign II: Late-Type and White Dwarf Stars
The Astronomical Journal, 1995 We present optical identifications of nine previously unidentified extreme ultraviolet (EUV) sources discovered during the Extreme Ultraviolet Explorer (EUVE) satellite surveys. The all-sky survey detected four of the sources and the more sensitive deep survey detected the other five sources.

Establishing the nature of companion candidates to X-ray emitting late B-type stars
, 2007 The most favored interpretation for the detection of X-ray emission from late B-type stars is that these stars have a yet undiscovered late-type companion (or an unbound nearby late-type star) that produces the X-rays.

The transmutation of dwarf galaxies : stellar populations [PDF]
, 2012 Transition-type dwarf (TTD) galaxies share characteristics of early-and late-type dwarfs. Thus, they are suspected to be the thread that connects them.

On the Possibility of an Upper Limit on Magnetically Induced Radius Inflation in Low-mass Stars
The Astrophysical JournalThe radii of low-mass stars are observed to be inflated above standard model predictions, especially in magnetically active stars. Typically, the empirical relative radius inflations Δ R / R are ≤10% but in (rare) cases may be ≥20%.
