The mass lost is often observed to be dust rich (Bedijn 1987). These stars are often heavily dust obscured in the optical and emit copiously in the IR; they are often so dusty that their SEDs peak at ~ 10 μm (Bedijn 1987).

WebTransfer of enough mass from a normal star onto a white dwarf companion can cause the latter to exceed the Chandrasekhar Limit of 1.4 solar masses and to explode as another kind of supernova. These "Type Ia" supernovae (the core collapse kind called "Type II") can hit absolute magnitude -19 and are invaluable to the study of the distances of galaxies and of … WebPycnopodia helianthoides, the largest of the sea stars, is radially symmetrical. The sunflower star has more arms than any other species, numbering between 15 and 24 (most sea stars have between 5 and 14), and is the heaviest known sea star, weighing about 5 kg.
