These variables as well as classical cepheids are important standard candles and have been used to establish the distance to the large magellanic cloud, globular clusters, open clusters, and the galactic center. Because they are low amplitude variables, they will be challenging to visual and ccd observers alike, but we hope it's a challenge you will all enjoy! Recent papers in delta scuti type stars. Delta scuti variables (dwarf cephid) are stars that pulsate from 0.003 to 0.9 magnitudes over a period of a few hours. Because of its moderate brightness, δ scuti should be easily visible from locations with dark skyes, while it can be barely visible, or not visible at all. I am not an astrophysicist but i believe that pulsations are due to the cyclical build up of opaque plasma in the chromosphere followed by ejection. A diverse class of very short period stars, the.
