Herschel observations of the nebula M1-67 around the Wolf-Rayet star WR 124
C. Vamvatira-Nakou, D. Hutsemekers, P. Royer +3
Infrared Herschel imaging and spectroscopic observations of the nebula M1-67 around the Wolf-Rayet star WR 124 have been obtained along with optical imaging observations. The infra…
The Herschel view of the nebula around the luminous blue variable star AG Carinae
C. Vamvatira-Nakou, D. Hutsemekers, P. Royer +5
Far-infrared Herschel PACS imaging and spectroscopic observations of the nebula around the luminous blue variable (LBV) star AG Car have been obtained along with optical imaging in…
The \b{eta} Lyrae-Type Eclipsing Binary EG Cep: New BVRI Photometry and Modelling
Chloi Vamvatira-Nakou, Alexios Liakos, Vassilios Manimanis +1
New BVRI CCD observations of the semi-detached eclipsing binary EG Cep are presented. The observed light curves are analyzed with the Wilson-Devinney program and new geometrical an…
A massive parsec-scale dust ring nebula around the yellow hypergiant Hen3-1379
D. Hutsemekers, N. L. J. Cox, C. Vamvatira-Nakou
On the basis of far-infrared images obtained by the Herschel Space Observatory, we report the discovery of a large and massive dust shell around the yellow hypergiant Hen3-1379 . T…
