2000), nearly a twin of the "Pistol Star," we also obtain a luminosity of around 1.7 x 106L© and an effective temperature of Teff ~ 105,00 K (see the line fits in Figure 13.2). It almost certainly has already shed a large fraction of its initial mass, forming the nebula that gave it its name in the process. We present new near-infrared data and analysis, which indicate that the Pistol Star is one of the most luminous stars known, adding another test point for massive star formation and stellar evolution theories. evolutionary tracks for very massive stars to determine the initial mass and age of the Pistol Star, and estimate and an age of 1.7 È 2.1 Myr. For star #362 (Geballe et al. I just did a double revert of the statement that this star radiates as much energy "in 1 sec" as the Sun in a year. The Pistol Star had such an impact when it was born that it changed scientific belief on how stars are formed. This web site was designed using frames. This correlates with the company's vision to alter and challenge traditional approaches to resolving specific technology problems — namely those challenges companies face with securing their global enterprise. One other of those stars meet the minimum criterion I set for my own list, an absolute bolometric magnitude (or equivalent given luminosity) of -11.8, and that star are listed here.

It is believed to be 100 times as massive as our Sun, and 10,000,000 times as bright! OB2-12. It is one of many massive young stars in the Quintuplet cluster in the central region of our galaxy. It is about 25,000 light years from Earth in the direction of Sagittarius.It would be visible to the naked eye as a fourth magnitude star but interstellar gases have blocked it from view. If your browser does not support frames, you may wish to upgrade to a browser that does support frames. For star #362 (Geballe et al. It was absurdly inconsistent with the luminosity claimed, as there are >31,500,000 seconds in a year, so I deleted the sentence. The Pistol Star is a blue hypergiant.It is one of the most luminous stars in the Milky Way galaxy.. Current contenders are:- LBV 1806-20, The Pistol Star and Cygnus. The Pistol star is a blue hypergiant.It is one of the most luminous stars in the Milky Way galaxy.. What is the biggest star we know?

It is one of many massive young stars in the Quintuplet cluster in the central region of our galaxy. The study of Figer, McLean & Morris, 1999, tabulates data for 33 stars they observed in the Quintuplet cluster (their table 3). The Pistol star is not the only bright star in the Qunituplet cluster. It almost certainly has already shed a large fraction of its initial mass, forming the nebula that gave it its name in the process. Click here to view this document w Answer: The largest known star (in terms of mass and brightness) is called the Pistol Star. The Pistol Star, also known as V4647 Sagittarii, is a blue hypergiant star located about 25,000 light years from Earth in the constellation Sagittarius.It is a candidate luminous blue variable (cLBV) and one of the most luminous stars known, with a luminosity 1,600,000 times that of the Sun.
In 1990, a star named the Pistol Star was known to lie at the center of the Pistol Nebula in the Milky Way Galaxy. We estimate an extinction of A K = 3.2 +/- 0.5 using the near-infrared colors of the star and of surrounding stars in the young Quintuplet cluster. 2000), nearly a twin of the "Pistol Star," we also obtain a luminosity of around 1.7 x 106L© and an effective temperature of Teff ~ 105,00 K (see the line fits in Figure 13.2). Pistol Star One of the most luminous and most massive stars in our Galaxy.It has been estimated to have a luminosity of up to 10 million times the luminosity of the Sun and an original mass of around 200 times the mass of the Sun. Which star has the greatest luminosity? Luminosity. The Pistol Star is a blue hypergiant star, one of the most luminous known in the Milky Way.It is one of many massive young stars in the Quintuplet cluster in the Galactic Center region.
