Embedded clusters: upgrading visual and infrared photometric analysis with Gaia DR2 and ASteCA
E. E. Giorgi, G. R. Solivella, A. Cruzado +3
Embedded clusters are groups of stars which have not dispersed yet the residual of the parental cloud where they were born so getting precise distances and properties of these grou…
Non-synchronous rotations in massive binary systems. HD93343 revisited
C. Putkuri, R. Gamen, N. I. Morrell +5
Context. Most massive stars are in binary or multiple systems. Several massive stars have been detected as doublelined spectroscopic binaries and among these, the OWN Survey has de…
The nearby Galaxy structure toward the Vela Gum nebula
E. E. Giorgi, G. R. Solivella, G. I. Perren +1
We report on photometry and spectroscopy for MK classification purposes carried out in the fields of five open clusters projected against the Vela Gum in the Third Galactic…
He II 4686 in eta Carinae: collapse of the wind-wind collision region during periastron passage
M. Teodoro, A. Damineli, J. I. Arias +23
The periodic spectroscopic events in eta Carinae are now well established and occur near the periastron passage of two massive stars in a very eccentric orbit. Several mechanisms h…
Optical spectroscopy of X-Mega targets in the Carina nebula - VII On the multiplicity of Tr 16-112, HD 93343 and HD 93250
G. Rauw, Y. Nazé, E. Fernández Lajús +4
We present the results of a spectroscopic monitoring campaign devoted to three O-type stars in the Carina nebula. We derive the full SB2 orbital solution of the binary system Tr 16…
The very massive X-ray bright binary system Wack 2134 (= WR 21a)
V. S. Niemela, R. C. Gamen, R. H. Barba +5
From the radial velocities of the N IV 4058 and He II 4686 emission lines, and the N V 4604-20 absorption lines, determined in digital spectra, we report the discovery that the X-r…
