We present optical spectroscopy of the dwarf nova HL Canis Majoris over a span of four years. The observations were made during standstill, outburst, and quiescence. We determine an orbital period of 0.2167867 ± 0.0000017 days, based on radial velocities determined from Hα, Hβ, and HeI λ 5876 emission. We also present equivalent widths of the spectral features in outburst and in quiescence. Sub...
متن کاملVY Canis Majoris: The Astrophysical Basis of Its Luminosity
The luminosity of the famous red supergiant VY CMa ( L ∼ 4− 5× 105L⊙) is well-determined from its spectral energy distribution and distance, and places it near the empirical upper luminosity limit for cool hypergiants. In contrast, its surface temperature is fundamentally ill-defined. Both contradict a recent paper by Massey, Levesque and Plez (2006). Implications for its location on the HR Dia...
متن کاملThe Emergent Flux and Effective Temperature of δ Canis Majoris
New angular diameter determinations for the bright southern F8 supergiant δ CMa enable the bolometric emergent flux and effective temperature of the star to be determined with improved accuracy. The spectral flux distribution and bolometric flux have been determined from published photometry and spectrophotometry and combined with the angular diameter to derive the bolometric emergent flux F = ...
متن کاملHIFISTARS Herschel/HIFI observations of VY Canis Majoris
Aims. The study of the molecular gas in the circumstellar envelopes of evolved stars is normally undertaken by observing lines of CO (and other species) in the millimetre-wave domain. In general, the excitation requirements of the observed lines are low at these wavelengths, and therefore these observations predominantly probe the cold outer envelope while studying the warm inner regions of the...
متن کاملSpatially resolved spectroscopy of Z Canis Majoris components ?
We present adaptive optics integral field spectrograph observations of the Z CMa binary in the 6203 Å-6528 Å band with a spectral resolution of 3200 and spatial resolution of 0.24′′, made with the OASIS instrument coupled to the PUE’O bonnette. Using the binary parameters derived from speckle interferometry, we are able to recover the spectrum of each component, in spite of a spatial sampling (...
