The following is a list of stars with resolved images, that is, stars whose images have been resolved beyond a point source. Aside from the Sun , observed from Earth , stars are exceedingly small in apparent size, requiring the use of special high-resolution equipment and techniques to image.
The star appears to be accreting from a protoplanetary disk of dust and gas, oriented face-on to Earth, which has been resolved in images from the ALMA observatory. TW Hydrae is accompanied by about twenty other low-mass stars with similar ages and spatial motions, comprising the " TW Hydrae association " or TWA, one of the closest regions of ...
The following is a list of particularly notable actual or hypothetical stars that have their own articles in Wikipedia, but are not included in the lists above. BPM 37093 — a diamond star Cygnus X-1 — X-ray source
Altair is one of the few stars for which a resolved image has been obtained. [29] In 2006 and 2007, J. D. Monnier and his coworkers produced an image of Altair's surface from 2006 infrared observations made with the MIRC instrument on the CHARA array interferometer; this was the first time the surface of any main-sequence star , apart from the ...
R Doradus (HD 29712 or P Doradus) is a red giant variable star in the far-southern constellation Dorado, close to the border with Reticulum. Its distance from Earth is 178 light-years (55 parsecs). Having a uniform disk diameter of 57 ± 5 mas, it is thought to be the extrasolar star with the largest apparent size as viewed from Earth.
Half the stars concentrate within inner core with an effective radius of 330 light-years (100 pc). [ 7 ] [ 8 ] Densities in the central stellar cusp increase steeply, exceeding 3×10 7 (that is, 30 million) M ☉ pc −3 (that is, per parsec cubed) at the smallest sub-radii resolved by HST , [ 9 ] and the half-light radius of this central star ...
This image tracks the life of a Sun-like star, from its birth on the left side of the frame to its evolution into a red giant on the right after billions of years. Red giants are evolved from main-sequence stars with masses in the range from about 0.3 M ☉ to around 8 M ☉. [9]
In particular, the lower limit of its 1.65–3.8 μm color of 3.1 magnitudes excludes background stars and most brown dwarfs. Spatially resolved images of the system from the Herschel Space Observatory [7] show evidence for a possible 2 belt system with a large clearing between the belts, similar to HR 8799. HD 95086 b is probably responsible ...
