    The Complex‐Heterozygotes of Oenothera grandiflora L'Her.

    Full text link
    Complex‐heterozygotes discovered in populations of O. grandiflora in Alabama are composed of a typical grandiflora (B) complex and an altered B complex which modifies the phenotype in the direction of O. villosa (A). A cytogenetic analysis of the new complex, designated B A , is reported including results of its compatibility with different plastomes. The evidence suggests that the B A complex resulted from hybridization between O. grandiflora and the pollen complex of the sympatric O. biennis .Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/106067/1/j.1438-8677.1992.tb00316.x.pd

    Neutron star mass and radius measurements from atmospheric model fits to X-ray burst cooling tail spectra

    Observations of thermonuclear X-ray bursts from accreting neutron stars (NSs) in low-mass X-ray binary systems can be used to constrain NS masses and radii. Most previous work of this type has set these constraints using Planck function fits as a proxy: both the models and the data are fit with diluted blackbody functions to yield normalizations and temperatures which are then compared against each other. Here, for the first time, we fit atmosphere models of X-ray bursting NSs directly to the observed spectra. We present a hierarchical Bayesian fitting framework that uses state-of-the-art X-ray bursting NS atmosphere models with realistic opacities and relativistic exact Compton scattering kernels as a model for the surface emission. We test our approach against synthetic data, and find that for data that are well-described by our model we can obtain robust radius, mass, distance, and composition measurements. We then apply our technique to Rossi X-ray Timing Explorer observations of five hard-state X-ray bursts from 4U 1702-429. Our joint fit to all five bursts shows that the theoretical atmosphere models describe the data well but there are still some unmodeled features in the spectrum corresponding to a relative error of 1-5% of the energy flux. After marginalizing over this intrinsic scatter, we find that at 68% credibility the circumferential radius of the NS in 4U 1702-429 is R = 12.4+-0.4 km, the gravitational mass is M=1.9+-0.3 Msun, the distance is 5.1 < D/kpc < 6.2, and the hydrogen mass fraction is X < 0.09.Comment: 15 pages, 11 figures, submitted to A&

    Cytological analysis of complex-heterozygotes in populations of Oenothera grandiflora ( Onagraceae ) in Alabama

    Genetic analysis of unusual complex-heterozygous genotypes in populations of O. grandiflora from Alabama (USA) has shown that these strains are composed of a typical grandiflora (B) complex and an altered B complex (designated as B A ) which probably contains genetic elements derived from an A genotype such as the beta complex of O. biennis group 1. Analysis of the meiotic configurations of artificial hybrids between the new strains and a series of complexes of known segmental arrangement allowed determination of the arrangements of the unknown complexes. These data are evidence for origin of the altered B complexes.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/41635/1/606_2004_Article_BF00937779.pd
