New Distant Companions to Known Nearby Stars. Ii. Faint Companions of Hipparcos Stars and the Frequency of Wide Binary Systems
We perform a search for faint, common proper motion companions of Hipparcos stars using the recently published LSPM-north catalog of stars with proper motion μ > 0.15 yr−1. Our survey uncovers a total of 521 systems with angular separations 3 < ∆θ < 1500, with 15 triples and 1 quadruple. Our new list of wide systems with Hipparcos primaries includes 130 systems identified here for the first tim...
متن کاملLifelong companions
The life of an RNA molecule is complicated. Once a newly synthesized eukaryotic RNA has emerged from the RNA polymerase in the nucleus, it will be processed, spliced, and exported into cytoplasm. In prokaryotes, transcribed RNA is synthesized directly in the cytoplasm. RNA molecules that serve as mRNAs have to be kept devoid of local structures that are inhibitory for ribosome scanning and tran...
متن کاملArtificial Companions
The paper concerns the closely related topics of the possibility of machines having identifiable personalities, and the possible future legal responsibilities of machines. As will become clear, I wish to explore these topics in terms which are basically those of computational linguistics; and by ‘machines’ here, I intend software entities, rather than robots, and in particular the sort of softw...
متن کاملThe Detectability of Planetary Companions of Compact Galactic Objects from Their Eeects on Microlensed Lightcurves of Distant Stars
We discuss a possible method for detection of dark companions of galactic objects of stellar mass. Such binary systems are likely to occur in the galactic disk and possibly also in the halo. The high incidence of binary and highermultiplicity systems in the solar neighborhood, if indicative of the galactic disk at large, implies that current searches for the gravitational microlensing signature...
متن کاملTiny travel companions
Since the first modern humans left their birthplace in Eastern Africa and slowly spread to populate every inhabitable place on the planet, Homo sapiens has been a migratory animal. Over thousands of years, these travellers unknowingly carried excess baggage on their journeys: countless microbes in and on their bodies, which evolved along with their host. By applying the tools of modern genomics...
