Stellar Family Portrait
New Extreme Imaging Techniques
The young star cluster Trumpler 14 is revealed in another stunning image. The amount of exquisite detail seen in this portrait, which beautifully reveals the life of a large family of stars captured through ESO’s VLT. A video zooming in after the jump.
This short sequence zooms in on the open young cluster of stars, Trumpler 14, which was imaged in great detail thanks to the Multi-Conjugate Adaptive Optics Demonstrator (MAD) mounted on ESO’s Very Large Telescope. Trumpler 14, inside the Carina Nebula, towards the constellation of Carina (the Keel), is located 8000 light-years away. It is the adaptive optics image that covers the largest area of sky so far.

Never before has such a large patch of sky been imaged using adaptive optics, a technique by which astronomers are able to remove most of the atmosphere's blurring effects.
Noted for harboring Eta Carinae — one of the wildest and most massive stars in our galaxy — the impressive Carina Nebula also houses a handful of massive clusters of young stars. The youngest of these stellar families is the Trumpler 14 star cluster, which is less than one million years old — a blink of an eye in the Universe’s history. This large open cluster is located some 8000 light-years away towards the constellation of Carina (the Keel).
A team of astronomers, led by Hugues Sana, acquired astounding images of the central part of Trumpler 14 using the Multi-conjugate Adaptive optics Demonstrator mounted on ESO’s Very Large Telescope (VLT). Thanks to MAD, astronomers were able to remove most of the blurring effects of the atmosphere and thus obtain very sharp images. MAD performs this correction over a much larger patch of the sky than any other current adaptive optics instrument, allowing astronomers to make wider, crystal-clear images.
Thanks to the high quality of the MAD images, the team of astronomers could obtain a very nice family portrait. They found that Trumpler 14 is not only the youngest — with a refined, newly estimated age of just 500 000 years — but also one of the most populous star clusters within the nebula. The astronomers counted about 2000 stars in their image, spanning the whole range from less than one tenth up to a factor of several tens of times the mass of our own Sun. And this in a region which is only about six light-years across, that is, less than twice the distance between the Sun and its closest stellar neighbor!
The most prominent star is the supergiant HD 93129A, one of the most luminous stars in the Galaxy. This titan has an estimated mass of about 80 times that of the Sun and is approximately two and a half million times brighter! It makes a stellar couple — a binary star — with another bright, massive star. The astronomers found that massive stars tend to pair up more often than less massive stars, and preferably with other more massive stars.
The Trumpler 14 cluster is undoubtedly a remarkable sight to observe: this dazzling patch of sky contains several white-blue, hot, massive stars, whose fierce ultraviolet light and stellar winds are blazing and heating up the surrounding dust and gas. Such massive stars rapidly burn their vast hydrogen supplies — the more massive the star, the shorter its lifespan. These giants will end their brief lives dramatically in convulsive explosions called supernovae, just a few million years from now.
A few orange stars are apparently scattered through Trumpler 14, in charming contrast to their bluish neighbors. These orange stars are in fact stars located behind Trumpler 14. Their reddened color is due to absorption of blue light in the vast veils of dust and gas in the cloud.
The technology used in MAD to correct for the effect of the Earth’s atmosphere over large areas of sky will play a crucial role in the success of the next generation of telescopes.
