These enormous stars emit up to 10 times more energy than the Sun and, so, are easy to study. Some of them, specifically the pulsating long-period variables, significantly change their size, brightness, and color within about a year, a time scale of interest to a single human being. Some aspects of the study of red giant stars are similar to the study of pre-main-sequence stars. For example, optical astronomy gives us a tantalizing glimpse of star forming regions but to really investi gate young stars and protostars requires infrared and radio astronomy. The same is true of post-main-sequence stars that are losing mass. Optical astronomers can measure the atomic component of winds from red giant stars that are undergoing mass loss at modest rates 6 (M $ 10- M9/yr.). But to see dust grains and molecules properly, 5 especially in stars with truly large mass loss rates, ~ 10- M9/yr, one requires IR and radio astronomy. As this stage of copious mass loss only lasts for ~105 years one might be tempted to ask, "who cares?". | | 出版日期 | Conference proceedings 1985 | | 关键词 | LOPES; Variation; astronomy; gravity; interferometry; optical interferometry; photometry; planet; radio astr | | 版次 | 1 | | doi | https://doi.org/10.1007/978-94-009-5428-1 | | isbn_softcover | 978-94-010-8896-1 | | isbn_ebook | 978-94-009-5428-1Series ISSN 0067-0057 Series E-ISSN 2214-7985 | | issn_series | 0067-0057 | | copyright | D.
