Discovery of an optical cocoon tail behind the runaway HD 185806
Z. T. Spetsieri, P. Boumis, A. Chiotellis +6
Studies on the circumstellar structures around evolved stars provide vital information on the evolution of the parent star and the properties of the local interstellar medium. In t…
Host galaxy magnitude of OJ 287 from its colours at minimum light
Mauri J. Valtonen, Lankeswar Dey, S. Zola +54
OJ 287 is a BL Lacertae type quasar in which the active galactic nucleus (AGN) outshines the host galaxy by an order of magnitude. The only exception to this may be at minimum ligh…
Linking the properties of accreting white dwarfs with the ionization state of their ambient medium
D. Souropanis, A. Chiotellis, P. Boumis +5
Steadily accreting white dwarfs (WDs) are efficient sources of ionization and thus, are able to create extended ionized nebulae in their vicinity. These nebulae represent ideal too…
