The Araucaria Project. Precise physical parameters of the eclipsing binary IO Aqr
D. Graczyk, P. F. L. Maxted, G. Pietrzynski +11
Our aim is to precisely measure the physical parameters of the eclipsing binary IO Aqr and derive a distance to this system by applying a surface brightness - colour relation. Our…
The Araucaria Project. Accurate stellar parameters and distance to evolved eclipsing binary ASAS J180057-2333.8 in Sagittarius Arm
K. Suchomska, D. Graczyk, R. Smolec +11
We have analyzed the double-lined eclipsing binary system ASAS J180057-2333.8 from the All Sky Automated Survey (ASAS) catalogue . We measure absolute physical and orbital paramete…
New spectroscopic and polarimetric observations of the A0 supergiant HD92207
S. Hubrig, A. F. Kholtygin, M. Schöller +5
Our recent search for the presence of a magnetic field in the bright early A-type supergiant HD92207 using FORS2 in spectropolarimetric mode revealed the presence of a longitudinal…
