Abstract

The development of a corrector for low-frequency variations in the star image at the input of ESPriF—the echelle spectropolarimeter of the BTA primary focus—is reported. New technical solutions have made it possible to extend the operating frequency range to 10 Hz for stars brighter than \(13^{\mathrm{m}}\).

ESPriF：BTA Primary Focus 的阶梯光栅分光偏振计。星图低频变化的校正

摘要

据报道，开发了一种针对 ESPriF（BTA 主焦点的中阶梯光栅分光偏振计）输入端星图低频变化的校正器。对于比\(13^{\mathrm{m}}\)更亮的恒星，新技术解决方案可以将工作频率范围扩展到10 Hz 。
