Study of three 2013 novae: V1830 Aql, V556 Ser and V809 Cep

BVRC IC photometry and low-, medium- and high-resolution echelle fluxed spectroscopy is presented and discussed for three faint, heavily reddened novae of the Fe ii-type which erupted in 2013. V1830 Nova Aql 2013 reached a peak V = 15.2 mag on 2013 Oct 30.3 ut and suffered from a huge E(B − V) ∼ 2.6 mag reddening. After a rapid decline, when the nova was ΔV = 1.7 mag below maximum, it entered a fl...
