Theta 1 Ori C is the dominant and most luminous star in the Orion star-forming region. The first recorded observation of a multiple star character of Theta1 Orionis, the bright stellar object in the Orion Nebula (M42), occurred on February 4, 1617, when it was observed and recorded as triple by Galileo Galilei (Galileo 1617, Fedele 1949, Ondra 1999, Mosher 2005), who did, however, not recognize the Orion Nebula due to unknown reasons. A possible model for the blueshifted emission is that it arises in a large-scale, dense shock front, provoked in some way by the wind of ^1Ori C. The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative Theta 1 Orionis C ; Data pengamatan Epos J2000; Rasi bintang: Orion: Asensio rekta: 05 h 35 m 16.5 s: Deklinasi −05° 23′ 24″ 41 Ori C, HR 1895, HD 37022, SAO 132314, V1016 Ori.

View our Privacy Policy. The combination of the Hei 2^3S column density, deduced from the 3889-Angstroms line, with the non-detection of Brgamma emission at the same velocities sets an upper limit on the electron density in this medium of 10^10 m^-3. By farthe leader of the pack is Theta-1 C, a great 40-solar-mass starwith a temperature of 40,000 Kelvin (making it the hottest "nakedeye" star, though the 4 are inseparable without optical aid), ahuge luminosity 210,000 times that of the Sun (85 percent of theTrapezium's total), and a 1000 … Even at R~10^6, the Hei absorption profile, associated with foreground gas at a heliocentric velocity of +3km s^-1, is very smooth, suggesting a simple broadening mechanism and homogeneity. A possible model for the blueshifted emission is that it arises in a large-scale, dense shock front, provoked in some way by the wind of ^1Ori C.Peer reviewe.

A clue to the origin of this emission is found in its spatial distribution: unlike the bright background nebular emission, the blueshifted component peaks symmetrically around the position of Theta^1Ori C, suggesting a physical association with the star.
