To achieve this, we built a virtual real experiment which can be performed from distance on any portable device. Students can connect to a webpage and choose a star from a list. After applying B and V filters they obtain the B and V magnitude. Consequently, they calculate the B-V index of a star and using a simple formula they estimate the star’s surface temperature. Furthermore, guided through a worksheet and with the use of Hertzsprung–Russell diagram they can estimate the radius and the age of the star.}, number={01}, journal={International Journal of Online and Biomedical Engineering (iJOE)}, author={Dintsios, Nikolaos and Artemi, Stamatia and Polatoglou, Hariton}, year={2018}, month={Jan.}, pages={pp. 162–178} }
