It has an apparent magnitude of 9.85 and can be seen with small telescopes. ==Characteristics== AS 314 was poorly studied until the year 2000, when Miroshnichenko et al. determined a distance for this star of around 10 kiloparsecs (32,600 light years), a luminosity 160,000 times that of Sun (), a radius 200 times the solar radius (), and an initial mass of 20 solar masses (). It's losing each year (in other words, every 50,000 years) through a very strong stellar wind.〔 It has an infrared excess, suggesting that it's shrouded in a circumstellar envelope of dust, which perhaps produced outbursts in the past as a luminous blue variable, because its location in the Hertzsprung–Russell diagram places it near the zone occupied by those stars;〔 however, it has not been classified as a ''bona fide'' luminous blue variable, but as a candidate.〔 The Hipparcos parallax and proper motions are large and imply a much closer, and hence less luminous, star.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「AS 314」の詳細全文を読む スポンサード リンク
