Bappu helped establish several astronomical institutions in India——including the Vainu Bappu Observatory named after him—and also contributed to the establishment of the modern Indian Institute of Astrophysics.

In a paper published in 1957, American astronomer Olin Chaddock Wilson and Bappu had described what would later be known as the Wilson-Bappu effect. The effect as described by L.V. Kuhi is: 'The width of the Ca II emission in normal, nonvariable, G, K, and M stars is correlated with the visual absolute magnitude in the sense that the brighter the star the wider the emission.
