Název v původním jazyce

High-resolution, near-infrared observations of B[e] supergiants

Popis výsledku v původním jazyce

B[e] supergiants stars are surrounded by disks formed from material released from the central object. To trace the properties of these disks, diverse emission features in the optical and near-infrared can be used. CO band emission is particularly valuable, because it defines the transition region between the atomic and molecular gas. We have recently started a campaign to obtain high-resolution near-infrared spectra for B[e] supergiant stars with confirmed CO emission. In this work, we present GEMINI/IGRINS spectra of CD-57 3107 and HD 62 623 and the physical parameters of their molecular disks obtained from detailed modeling of their CO band emission. Moreover, we report on the detection of 13CO emission in both stars, reinforcing the evolved nature of these objects.nn
