San Pedro meeting on Wide Field Variability Surveys: Some concluding comments

Blog Article

This is a written version of the closing talk at the 22nd Los Alamos Stellar pulsation conference on wide field variability surveys.It comments on some of the issues which arise from the meeting.These include the need merlin wizard costume for attention to photometric standardization (especially in the infrared) and the somewhat controversial problem of statistical bias in the use of parallaxes (and other methods of distance determination).

Some major advances in the use of pulsating variables to study Galactic structure are mentioned.The paper includes a clarification of apparently conflicting results from classical Cepheids and RR Lyrae stars in the inner Galaxy and bulge.The importance of understanding non-periodic phenomena in variable stars, particularly asymptotic giant branch variables and R Coronae Borealis stars, iphone 13 pro max price winnipeg is stressed, especially for its relevance to mass-loss in which pulsation may only play a minor role.
