Research

Much of Winget's research concerns the study of

pulsating white dwarf A pulsating white dwarf is a white dwarf star whose luminosity varies due to non-radial gravity wave pulsations within itself. Known types of pulsating white dwarfs include DAV, or ZZ Ceti, stars, with hydrogen-dominated atmospheres and the s ...
. After becoming a faculty member at the University of Texas, he and his colleagues discovered
GD 358 GD 358 is a variable white dwarf star of the DBV type. Like other pulsating white dwarfs, its variability arises from non-radial gravity wave pulsations within the star itself. GD 358 was discovered during the 1958–1970 Lowell ...

s was predicted to exist before any instances of it were observed. With Ed Nather, his colleague at University of Texas, Winget introduced the technique for studying the seismology and the inner structure of white dwarfs called "

". The technique involves coordinating a network of small telescopes around the world to capture small variations in the light output of a white dwarf caused by its seismic oscillations. One of Winget's projects involves studying white dwarfs using the Z machine pulsed-power electromagnetic wave generator at the Sandia National Lab in
