WASP-39b is also notable for having an extremely low density, near that of WASP-17b.While WASP-17b has a density of 0.13 0.06 g/cm 3, WASP-39b has a slightly higher Each star is assigned a spectral class (from the older Harvard spectral classification, which did not include luminosity) and a luminosity class using Roman numerals as explained below, forming the star's spectral type.. Other modern stellar classification systems, such as the UBV system, are based The primary emission lines used to distinguish the WC sub-types are C II 426.7 nm, C III at 569.6 nm, C III/IV465.0 nm, C IV at 580.1581.2 nm, and the O V (and O III) blend at 557.2559.8 nm. As a result, the core temperature of main sequence stars only varies from 4 million kelvin for a small M-class star to 40 million kelvin for a massive O-class star.

Drake used a radio telescope 26 metres (85 ft) in diameter at Green Bank, West Virginia, to examine the stars Tau Ceti and Epsilon Eridani near the 1.420 gigahertz marker frequency, a region of the radio spectrum dubbed the "water hole" due to its proximity to the hydrogen and hydroxyl radical spectral lines. The eponymous star for classical Cepheids, Delta Cephei, was discovered to be variable by John Goodricke a few months later. The WC spectral sequence was expanded to include WC4WC11, although some older papers have also used WC1WC3.
