"The B[e] Phenomenon: Forty Years of Studies"27 June - 1 July 2016 Prague, Czech Republic

Among astrophysical phenomena discovered in the second half of the 20-th century the B[e] phenomenon is observed in stars with the widest variety of masses and evolutionary stages. This phenomenon is defined as the presence of forbidden emission lines, along with permitted ones, and an excess infrared radiation due to circumstellar dust in the spectra of hot stars. Many objects with these features have been discovered in the Milky Way and nearby galaxies. Their observed properties, unusual in many cases, challenge minds of astrophysicists and provide an invaluable material for further exploration of the Universe. 
The website: is devoted to the 3rd international conference on studies of objects with the B[e] phenomenon that will take place in Prague in the summer of 2016. Astronomers working in related fields of astrophysics are welcome to join discussions on recent progress in observations and interpretation of these spectacular objects.
