摘要:

在这张海报中,我们展示了我们对IC 1613中三颗早期大质量恒星的分析结果,这些恒星的光谱是用VIMOS观测的,并用CMFGEN和FASTWIND分析的。其中一个目标导致了可能的LBV,另外两个是具有意外强风的恒星。恒星似乎被CNO产品严重污染。我们的初步结果可能代表了对恒星大气理论的挑战,但它们仍然需要通过分析更多的物体和更完整的参数空间来证实。

英文摘要:

In this poster we present the results of our analyses of three early massive stars in IC 1613, whose spectra have been observed with VIMOS and analyzed with CMFGEN and FASTWIND. One of the targets resulted a possible LBV and the other two are Of stars with unexpectedly strong winds. The Of stars seem to be strongly contaminated by CNO products. Our preliminary results may represent a challenge for the theory of stellar atmospheres, but they still have to be confirmed by the analysis of more objects and a more complete coverage of the parameter space.
