Bayesian model checking: A comparison of tests
Leon B. Lucy
Two procedures for checking Bayesian models are compared using a simple test problem based on the local Hubble expansion. Over four orders of magnitude, p-values derived from a glo…
Projected distances to host galaxy reduce SNIa dispersion
R. Hill, H. Shariff, R. Trotta +8
We use multi-band imagery data from the Sloan Digital Sky Survey (SDSS) to measure projected distances of 302 supernova type Ia (SNIa) from the centre of their host galaxies, norma…
Irradiated stars with convective envelopes
L. B. Lucy
The observed radii of M dwarfs in eclipsing binaries exceed predicted radii by ~ 5%. To investigate this anomaly, the structure of low-mass stars irradiated by a close companion is…
Frequentist tests for Bayesian models
L. B. Lucy
Analogues of the frequentist chi-square and F tests are proposed for testing goodness-of-fit and consistency for Bayesian models. Simple examples exhibit these tests' detection of…
Mass fluxes for O-type supergiants with metallicity Z = Z_{\sun}/5
L. B. Lucy
A code used previously to predict O-star mass fluxes as a function of metallicity is used to compute a grid of models with the metallicity of the Small Magellanic Cloud (SMC). Thes…
Mass estimates for visual binaries with incomplete orbits
L. B. Lucy
The problem of estimating the total mass of a visual binary when its orbit is incomplete is treated with Bayesian methods. The posterior mean of a mass estimator is approximated by…
Bayesian inference for orbital eccentricities
L. B. Lucy
Highest posterior density intervals (HPDI's) are derived for the true eccentricities of spectroscopic binaries with measured values e ~ 0. These yield upper limits when e is below…
Coronal winds powered by radiative driving
L. B. Lucy
A two-component phenomenological model developed originally for zeta Puppis is revised in order to model the outflows of late-type O dwarfs that exhibit the weak-wind phenomenon. W…
Mass fluxes for hot stars
L. B. Lucy
In an attempt to understand the extraordinarily small mass-loss rates of late-type O dwarfs, mass fluxes in the relevant part of (T_{eff}, g)-space are derived from first principle…
Iterative techniques for the decomposition of long-slit spectra
L. B. Lucy, J. R. Walsh
Two iterative techniques are described for decomposing a long-slit spectrum into the individual spectra of the point sources along the slit and the spectrum of the underlying backg…
Identification of a strong emission line at 2.8935 mu in the spectrum of the Orion Nebula
L. B. Lucy
A strong emission line at 2.8935 mu discovered by Rubin et al. (2001) in an ISO SWS02 spectrum of the Orion Nebula is identified as the 4p - 4s multiplet of the O I triplets. Line…
An iterative technique for solving equations of statistical equilibrium
L. B. Lucy
Superlevel partitioning is combined with a simple relaxation procedure to construct an iterative technique for solving equations of statistical equilibrium. In treating an -leve…
