The nearby star system Fomalhaut -- of special interest for its unusual exoplanet and dusty debris disk -- has been discovered to be not just a double star, as astronomers had thought, but one of the widest triple stars known. The results are described in a paper recently accepted for ...
Star System Exoplanet(s) Fomalhaut is abinaryormultiple star system. The list below may not include all the stars, only those that are recorded on this site. TW Piscis Austriniis the main star in the system and the one that is designated as 'A'. It can also refer to the whole system...
Indeed, while astronomers expected to see a lot of similar intricate details between our solar system and the Fomalhaut star system, they were surprised to find that it is more complicated than previously thought, in part because they discovered it has an unexpectedly convoluted asteroid belt. From...

For a sense of scale, each pixel of the image is over 50 million kilometres wide and our entire solar system out to Pluto would fit into a space roughly half the size of the intermediate ring. As in the previous image, the direct light from the star ...
star,HR 8721, is yellow and orbits at a distance of about 0.9 light-year. A belt of dust orbits between 19.9 and 23.6 billion km (12.4 and 14.7 billion miles) from the star. The dust belt appears to be filled withcometslike thesolar system’sKuiper belt. Itsinfraredbrightness indicates ...
It was originally catalogued as a lone red dwarf, until October 2013, when Eric Mamajek announced that the star had a distance, velocity and color-magnitude position consistent with it being part of the Fomalhaut system. 它最初被當成一顆單獨的紅矮星編入星表,直到2013年10月,在Eric Mamajek宣...
Here, we show how the system would appear as if viewed face-on utilizing orbit fitting to determine the inclination and position angle of the system. 23/25 color image This is a color image, produced using the 23.0 and 25.5 micron observations. Enhanced images Courtesy of Adam Block, we al...
We plan to continue observing the Fomalhaut system to pro- vide even better constraints on the rotation of the central star, as well as to extend the study to other fast rotating stars hosting resolved debris disks. Acknowledgements. JBLB warmly thanks the complete VLTI team of the Paranal ...
