OpenAI has released the Chat Generative Pre-trained Transformer (ChatGPT) and revolutionized approach in artificial intelligence to human-model interaction. Several publications on ChatGPT evaluation test its effectiveness well-known natural language processing (NLP) tasks. However, existing studies are mostly non-automated tested a very limited scale. In this work, we examined ChatGPT's capabi...

Metal-free stars are assumed to evolve at constant mass because of the very low stellar winds. This leads to large CO-core mass at the end of the evolution, so primordial stars with an initial mass between 25 and 85 M are expected to end as direct black holes, the explosion energy being too weak to remove the full envelope. We show that when rotation enters into play, some mass is lost because ...
