In earlier papers, we presented a binary evolutionary code for the purpose of reproducing the orbital parameters, masses, radii, and location in the Hertzsprung Russell diagram (abbreviated as HRD) of well-observed Algol systems. In subsequent versio

C46 was a Commission of the Executive Committee of the IAU under Division XII (Union-Wide Activities), then after 2012 under Division C (Education, Outreach, and Heritage). It was the only commission dealing exclusively with astronomy education; a pr

Using a population number synthesis code with detailed binary evolution, we calculate the distribution of the number of Type Ia supernovae as a function of time after starburst. This is done for both main progenitor scenarios (single degenerate and d

A brief analysis is given of the need for more trained people in science and technology versus the declined interest in studying sciences. In highlighting some of the aspects of research in astronomy, arguments are presented why astronomy education i

The IAU Commission 46 Program Group International Schools for Young Astronomers (ISYA) was created in 1967 (Gerbaldi 2008). During the period 2006 till August 2008 two ISYAs took place, one in Malaysia and a second one in Turkey.

We have put on CDS a catalog containing 561 evolutionary models of binaries: J/A+A/487/1129 (Van Rensbergen+, 2008). The catalog covers a grid of binaries with a B-type primary at birth, different values for the initial mass ratio and a wide range of

It has been established that Algols, issuing from a binary with a B‐type primary at birth, show more observed systems at large mass ratios than calculated with the conservative assumption, where no mass and angular momentum leaves the system. We ha
