SCORPIO - II. Spectral indices of weak Galactic radio sources

Autor: Cavallaro, F. Trigilio, C. Umana, G. Franzen, T.M.O. Norris, R.P. Leto, P. Ingallinera, A. Buemi, C.S. Marvil, J. Agliozzo, C. Bufano, F. Cerrigone, L. Riggi, S.

In the next few years the classification of radio sources observed by the large surveys will be a challenging problem and spectral index is a powerful tool for addressing it. Here we present an algorithm to estimate the spectral index of sources from multiwavelength radio images. We have applied ...

The Luminous Blue Variable RMC 127 as Seen with ALMA and ATCA

Autor: Agliozzo, C. Trigilio, C. Pignata, G. Phillips, N.M. Nikutta, R. Leto, P. Umana, G. Ingallinera, A. Buemi, C. Bauer, F.E. Paladini, R. Noriega-Crespo, A. Prieto, J.L. Massardi, M. Cerrigone, L.

We present ALMA and ATCA observations of the luminous blue variable RMC 127. The radio maps show for the first time the core of the nebula and evidence that the nebula is strongly asymmetric with a Z-pattern shape. Hints of this morphology are also visible in the archival Hubble Space Telescope i...

Exploring the multifaceted circumstellar environment of the luminous blue variable HR Carinae

Autor: Buemi, C.S. Trigilio, C. Leto, P. Umana, G. Ingallinera, A. Cavallaro, F. Cerrigone, L. Agliozzo, C. Bufano, F. Riggi, S. Molinari, S. Schillirò, F.

We present a multiwavelength study of the Galactic luminous blue variable HR Carinae, based on new high-resolution mid-infrared (IR) and radio images obtained with the Very Large Telescope (VLT) and the Australia Telescope Compact Array (ATCA), which have been complemented by far-infrared Hersche...

New ATCA, ALMA and VISIR observations of the candidate LBV SK-67 266 (S61): The nebular mass from modelling 3D density distributions

Autor: Agliozzo, C. Nikutta, R. Pignata, G. Phillips, N.M. Ingallinera, A. Buemi, C. Umana, G. Leto, P. Trigilio, C. Noriega-Crespo, A. Paladini, R. Bufano, F. Cavallaro, F.

We present new observations of the nebula around the Magellanic candidate Luminous Blue Variable S61. These comprise high-resolution data acquired with the Australia Telescope Compact Array (ATCA), the Atacama Large Millimetre/Submillimetre Array (ALMA), and the VLT Imager and Spectrometer for mi...

Spectroscopic and photometric oscillatory envelope variability during the S Doradus outburst of the luminous blue variable R71

Autor: Mehner, A. Baade, D. Groh, J.H. Rivinius, T. Hambsch, F.-J. Bartlett, E.S. Asmus, D. Agliozzo, C. Szeifert, T. Stahl, O.

Context. Luminous blue variables (LBVs) are evolved massive stars that exhibit instabilities that are not yet understood. Stars can lose several solar masses during this evolutionary phase. The LBV phenomenon is thus critical to our understanding of the evolution of the most massive stars. Aims. ...
