The Scintillation of Stars [PDF]
IN a recent communication in Nature1, Dr. A. H. R. Goldie has suggested that the scintillation of stars may be associated with waves at an interface between two currents of air which have a difference of temperature of the order of 5–7° F. “Such waves,” he writes, “should not uncommonly have an amplitude of the order of up to 500–1,000 ft.

The single star path to Be stars [PDF]
Context. Be stars are rapidly rotating B main sequence stars that show line emission due to an outflowing disc. By studying the evolution of rotating single star models, we can assess their contribution to the observed Be star populations. Aims. We identify the main effects that cause single stars to approach critical rotation as functions of initial ...

This paper reports on a health literacy study that explored adolescents’ conceptualizations of health information appraisal as a social practice in Latvia. The study was guided by phenomenography, a qualitative research approach used to describe people’s

Evidence for quark-matter cores in massive neutron stars [PDF]
The theory governing the strong nuclear force—quantum chromodynamics—predicts that at sufficiently high energy densities, hadronic nuclear matter undergoes a deconfinement transition to a new phase of quarks and gluons1.

INTRINSIC COLORS, TEMPERATURES, AND BOLOMETRIC CORRECTIONS OF PRE-MAIN-SEQUENCE STARS [PDF]
We present an analysis of the intrinsic colors and temperatures of 5–30 Myr old pre-main-sequence (pre-MS) stars using the F0- through M9-type members of nearby, negligibly reddened groups: the η Cha cluster, the TW Hydra Association, the β Pic Moving ...

Measuring neuropsychiatric symptoms in patients with early cognitive decline using speech analysis
Background Certain neuropsychiatric symptoms (NPS), namely apathy, depression, and anxiety demonstrated great value in predicting dementia progression, representing eventually an opportunity window for timely diagnosis and treatment.

Tree and 1-loop fundamental BCJ relations from soft theorems
We provide a new derivation of the fundamental BCJ relation among double-color-ordered tree amplitudes of bi-adjoint scalar theory, based on the leading soft theorem for external scalars. Then, we generalize the fundamental BCJ relation to 1-loop Feynman

Tidal Deformabilities and Radii of Neutron Stars from the Observation of GW170817. [PDF]
We use gravitational-wave observations of the binary neutron star merger GW170817 to explore the tidal deformabilities and radii of neutron stars.

Protoneutron stars and neutron stars [PDF]
Abstract We find constraints on minimum and maximum mass of ordinary neutron stars imposed by their early evolution (protoneutron star stage). We calculate models of protoneutron stars using a realistic standard equation of state of hot, dense matter valid for both supranuclear and subnuclear densities.
