The first direct observation of one of these bodies, one in 47 Tucanae, was made on October 29, 1997 using the FOS.

The collision and slow coalescence models seek to explain their formation; both are supported by the fact that these are more numerous in regions of high density, like the cores of globular clusters. These stars, exemplified by those in NGC 6397 and BSS 19, seem to contradict most theories of stellar evolution; they fall along the main sequence despite being beyond turnoff points. FTP, what is this class of stars, which are significantly hotter than neighboring cluster stars with the same luminosity and, as a consequence, display a characteristic color?
