Stellar Evolution and Evolved Stars

Page history last edited by pamela Klaassen 1 year, 10 months ago

Below is a list of suggested science cases provided by the AtLAST community. If/when adding your own suggestions, please read through the current list to ensure you're not duplicating a case, and use the template below for structuring your input.

 


Title: My Contributed Science Case

Summary: Here I'm going to regale you with a tale of the amazing contributions to my field that the AtLAST telescope will be able to provide. There are a lot of specifics in this summary, but I'm striving to keep it short and succinct. I also don't need any figures or tables to drive my point home.

Title: The origin of dust and the connection to circumstellar envelopes around low-mass evolved stars

Summary: Low-mass evolved stars expel a large amount of dust in their last stages of evolution, building up a large circumstellar envelope (CSE). The dust grains replenish the ISM with new material, and form the seeds for new stars and planets. They also provide a means for complex molecules to survive the interstellar radiation field. The extended CSEs are cool (30-70K) and emit at submm wavelengths. Additionally, the properties of large grains around evolved stars in the submm are not well studied. A 30-50m single-dish telescope would provide the spatial (5-8" at 350 GHz) resolution and the sensitivity to with bolometer arrays efficiently map the CSEs around evolved stars.
