Orbits for 615 halo and high-velocity disk stars have been numerically integrated in two different models for the galactic mass distribution, both satisfying recent observational constraints for the rotation curve and the perpendicular force (Allen and Martos 1986, Allen and Santill谩n 1991). In ...
Molecular line CN, CS and mm continuum observations of two intermediate- to high-mass star-forming regions - IRAS20293+3952 and IRAS19410+2336 - obtained with the Plateau de Bure Interferometer at high spatial resolution reveal interesting characteristics of the gas and dust emission. In spite of...
nucleosynthesis-powered, and free neutron decay-powered models, and discriminating between them is only possible by using UV observations performed in the first hours after the merger of neutron stars (Metzger 2019; Dorsman et al. 2023
We have examined star formation in two very luminous (M_V=-22 to -23) Sc-type spiral galaxies, NGC 801 and UGC 2885, using ultra-deep Halpha images. We combine these with UBV and 2MASS JHK images and HI maps to explore the star formation characteristics

These dwarfs are common throughout the universe, but now Mark Hollands at the University of Warwick, UK, and his colleagues have discovered a specimen 150 light years from Earth with some very peculiar characteristics. Advertisement It has a mass about double the average for a white...
This component, represented by a power law with a photon index of $\\sim 2.4$, may belong to the two sources. The characteristics of both the power-law and ultrasoft components strongly indicates that the two sources are black-hole candidates in high-mass X-ray binaries. 展开 ...
Studying these energy conditions is necessary to learn about the characteristics of spacetime and the matter sources that create it. In general relativity, the NEC is seen to be the most important of these criteria for wormhole solutions because of its association with the energy density necessary ...
Characteristics of sequence data Microbiota in two common starfish species and their surrounding seawater was studied using 16S rRNA gene amplicon sequencing. A total of 2,473,889 quality-filtered sequence reads were obtained from 34 samples (Supplementary Table2). Rarefaction curves showed that most ...
