Stars ’ - Have They Been Discovered ?
Recently there is a suggestion about the star RXJ1856.5−3754, being a possible candidate for quark star. While from the estimates of the radiation radius, given by the authors, it does not seem to fit with any of the known models for such stars, the mass radius diagram admits the possibility of this being a quark star of mass M ⊙ < M < 1.4M ⊙ , provided the radius mentioned is the actual radius...
متن کاملStrange Stars ’ - have they been discovered ?
Recently there have been controversial claims about the nature of the isolated compact star RXJ1856.5−3754, with one group claiming it to be a strange star (Drake et al., 2002) while the other asserting it to be a normal neutron star (Walter & Lattimer, 2002). The controversy arises mainly due to the distance estimate, which in turn is used to resolve the measured angular diameter, and thus the...
متن کاملHow environmental hazards in childhood have been discovered: carcinogens, teratogens, neurotoxicants, and others.
Review of the literature reveals that environmental hazards cause adverse health effects that include sterility, infertility, embryotoxicity, low birth weight, skin lesions, neurodevelopmental defects, immunologic disorders, cancer, and fear of late effects. They have been identified mostly by astute practitioners but also by a bacteriologist, an animal experimentalist, 5 factory workers in chi...
متن کاملFlavor - singlet hybrid baryons may already have been discovered
The splittings between the spin 1/2 and spin 3/2 iso-singlet baryons Λs(1405) and Λs(1520), and their charmed counterparts Λc(2593) and Λc(2625), have been a theoretical conundrum. Here we investigate the possibility that the QCD binding of color octets comprised of three quarks in a flavor singlet configuration is stronger than previously envisaged, allowing these states to be interpreted as h...
