Two spectra of the star BM Ori were obtained with the 2.6-m Crimean Astrophysical Observatory telescope near its maximum eclipse phase. The light detector was a CCD array. The wavelength range 5305–5373 Å was chosen in such a way that it contained no strong primary lines. Optimum filtration of the spectra yielded a signal-to-noise ratio of ∼300. Eighteen secondary lines are seen in the spectrum. Atmospheric parameters of the secondary star were determined: Teff=5740 K and logg=3.0; the… 
A spectroscopic study of the secondary star of BM Ori: Preliminary results
Two CCD spectra of the star BM Ori were obtained with the echelle spectrograph of the 6-m telescope. In one of the spectra, a large proportion of lines are distorted by emission. The emission
Masses and radii of the components of 1016 Ori
AbstractOn January 2/3, 2001, eight spectra of the star V 1016 Ori were taken with the 2.6-m Crimean Astrophysical Observatory telescope on the descending branch of its eclipse. The spectral range
X-Ray Emission from Early-Type Stars in the Orion Nebula Cluster
The X-ray properties of twenty ~1 Myr old O, B, and A stars of the Orion Trapezium are examined with data from the Chandra Orion Ultradeep Project (COUP). On the basis of simple theories for X-ray

We have imaged an area ~5 arcmin2 at the center of the Trapezium cluster in Orion in the K band using the University of Hawaii (UH) adaptive optics system at the UH 2.2 m telescope. Our survey
BM orionis: The enigmatic eclipsing binary in the trapezium
The enigma of BM Ori: namely, the apparent absence of spectral lines of a cooler component in spite of the considerable duration of approximately constant light during primary eclipse: is partially
BINARY STARS IN THE ORION TRAPEZIUM CLUSTER CORE
We have obtained high angular resolution (013 FWHM) near-infrared images of the central ~40'' × 40'' of the Trapezium cluster, using a speckle holography technique that we describe in detail. A
BM ORIONIS, THE ECLIPSING BINARY IN THE TRAPEZIUM.
Photoelectric UBV observations of BM Orionis were obtained by offsetting in a consistent manner which corrected for both nebulosity and scattered light. A complete li ht curve was obtained in V, with
Interpretation of BM orionis
The entire light curve of the BM Ori system both inside and outside primary and secondary eclipses has been examined on the basis of two models for the disk around the secondary component: one with
High resolution near-infrared imaging of the trapezium: A stellar census
We present high spatial resolution (0.35 and 0.65 arcsec full width at half maximum (FWHM)) near-infrared images of the central 0.2x0.2 pc of the Trapezium Cluster in the Orion Nebula, centered on
The case for a black hole in BM Orionis
Earlier photometric and spectroscopic observations of the binary BM Ori are interpreted in terms of a thin disk model for the object which causes the eclipses. It is shown that the secondary mass,
