Unusually Wide Binaries: Are They Wide or Unusual?
We describe an astrometric and spectroscopic campaign to confirm the youth and association of a complete sample of candidate wide companions in Taurus and Upper Sco. Our survey found fifteen new binary systems (3 in Taurus and 12 in Upper Sco) with separations of 3-30 (500-5000 AU) among all of the known members with masses of 2.5-0.012 M⊙. The total sample of 49 wide systems in these two regio...
متن کاملToxic Christmas and New Year Holiday Plants...or Are They?
Background: Poinsettia (Euphorbia pulcherrima), holly (Ilex opaca) and mistletoe (Phoradendron flavescens) adorn homes during the Christmas and New Year holiday season and create the potential for curious children to sample their colorful leaves and enticing berries. This study was aimed to review the American Association of Poison Control Centers National Poison Data System (AAPCC NPDS) to des...
متن کاملDrosophila genome-wide RNAi screens: are they delivering the promise?
The emergence of RNA interference (RNAi) on the heels of the successful completion of the Drosophila genome project was seen by many as the ace in functional genomics: Its application would quickly assign a function to all genes in this organism and help delineate the complex web of interactions or networks linking them at the systemic level. A few years wiser and a number of genome-wide Drosop...
متن کاملWide binaries in the Orion Nebula Cluster
Using proper motion data for 894 stars in the Orion Nebula Cluster (ONC) compiled by Jones & Walker in 1988, we search for binaries with apparent separations in the range 1000–5000 AU, and find an upper limit of three. Using a Monte Carlo method, we test the consistency of this result with two hypotheses: i) that the cluster contains a binary population identical to that found in the solar neig...
متن کاملSpectroscopic Subsystems in Nearby Wide Binaries
Radial velocity (RV) monitoring of solar-type visual binaries has been conducted at the CTIO/SMARTS 1.5-m telescope to study short-period systems. Data reduction is described, mean and individual RVs of 163 observed objects are given. New spectroscopic binaries are discovered or suspected in 17 objects, for some of them orbital periods could be determined. Subsystems are efficiently detected ev...
