NGC 2547 is a southern open cluster in Vela, discovered by Nicolas Louis de Lacaille in 1751 [2] [3] from South Africa. The star cluster is young with an age of 20-30 million years. [4] Observations with the Spitzer Space Telescope showed a shell around the B3 III/IV-type star HD 68478. This could be a sign of recent mass loss in this star.

NGC 2547 是一個位於南半球天空的 疏散星團，位於 船帆座。 該星團由法國天文學家 尼可拉·路易·拉卡伊 於1751至1752年間在南非發現。 該星團的角直徑約20'，視星等4.7等。 年齡只有2000至3500萬年 [1]。 NGC 2547在天球上的位置。 NGC 2547中的恆星NGC 2547-ID8周圍小行星相互碰撞形成行星的想像圖。 2012至2013年間觀測資料製作的紅外線亮度的時序變化圖，被認為是星團內恆星NGC 2547-0ID8周圍發生小行星碰撞。 NGC 2547疏散星團全範圍影像。 ^ Young, …

NGC 2547 is a Open Cluster in the Vela constellation. NGC 2547 is situated south of the celestial equator and, as such, it is more easily visible from the southern hemisphere. Given its visual magnitude of 4.7, NGC 2547 is barely visible to the naked eye, easily visible with the help of …

2013年3月27日 · While NGC 2547 contains many hot stars that glow bright blue, a telltale sign of their youth, you can also find one or two yellow or red stars, which have already evolved to become red giants.

2MASS J08090250-4858172 (also called NGC 2547–ID8) is a star in the cluster NGC 2547. In 2014 it was reported that the star had brightened in the infrared. This was interpreted as a collision between planetesimals. [2]

NGC 2547 is a large (20') and super bright (4.7 Mag) open cluster in the constellation Vela. NGC 2547 was formed about 30 million years ago. NGC 2547 contains many stars with debris disks. Thus, NGC 2547 contains nine M-dwarfs with 24 μm excess.

2013年3月27日 · The star cluster NGC 2547 lies in the southern constellation of Vela (The Sail), about 1500 light-years from Earth, and is bright enough to be easily seen using binoculars.

2004年9月1日 · We present Spitzer observations of the young cluster NGC 2547, obtaining photometry at 3.6, 4.5, 5.8, 8.0, and 24 μm, reaching significantly fainter infrared sensitivities than previous studies. With these observations, we investigate the disk frequency in this cluster.
