The atmosphere, the p-factor and the bright visible circumstellar environment of the prototype of classical Cepheids δ Cep

Even ≃ 16000 cycles after its discovery by John Goodricke in 1783, δ Cep, the prototype of classical Cepheids, is still studied intensively in order to better understand its atmospheric dynamical structure and its environment. Using HARPS-N spectroscopic measurements, we have measured the atmospheri...
