In 1961 he published the Van Biesbroeck's star catalog. In this he cataloged a number of very faint stars, known by the VB numbers he assigned to them upon discovery. One notable star he discovered was the very small red dwarf secondary star, VB 10, also known as Gliese (GJ) 752B, of the primary star, Wolf 1055 (Gliese (GJ) 752A). This star was unique in that its absolute magnitude of 19 was the lowest of any star then known and still thought to be the lowest possible for any star. VB 10 was given the designation of Van Briesbroeck's Star to honor him for this work and his work with double stars.

Famous quotes containing the word discoveries:
“It is remarkable what a value is still put upon wood even in this age and in this new country, a value more permanent and universal than that of gold. After all our discoveries and inventions no man will go by a pile of wood. It is as precious to us as it was to our Saxon and Norman ancestors. If they made their bows of it, we make our gun-stocks of it.”
—Henry David Thoreau (1817–1862)
“Ah, I fancy it is just the same with most of what you call your “emancipation.” You have read yourself into a number of new ideas and opinions. You have got a sort of smattering of recent discoveries in various fields—discoveries that seem to overthrow certain principles which have hitherto been held impregnable and unassailable. But all this has only been a matter of intellect, Miss West—superficial acquisition. It has not passed into your blood.”
—Henrik Ibsen (1828–1906)
“However many discoveries we may have made in the land of self-love, there remain uncharted territories.”
—François, Duc De La Rochefoucauld (1613–1680)
