Esipov, V. F.; Ikonnikova, N. P.; Tatarnikov, A. M. +7 more

We present the results of a UBVRcIc and JHKLM photometric monitoring campaign conducted in 2016-2020, low-resolution spectroscopy, and an analysis of the ASAS-3 and ASAS-SN photometric data for the semiregular variable and post-AGB candidate AU Vul (IRAS 20160+2734). The star is shown to experience quasi-periodic brightness oscillations with a var…
