The temperature classification of early-type stars is based on Balmer jump (Balmer discontinuity). To measure it one must have two bandpasses placed in the ultraviolet, one beyond the Balmer jump (U magnitude) and another after the jump (X magnitude).. The Y bandpass is near the breakpoint of the interstellar …

Balmer jump concept from the Astronomy knowledge base

웹9시간 전 · LANCASTER, Ohio -- There’s an urban legend about the “boiling frog,” an experiment that involves putting a frog in a pot of boiling water, where it quickly jumps out. … 웹We report on the effects of two disk properties on the continuum linear polarization signature of classical Be stars. First, we investigate the effect of including metallicity in computing the thermal structure of the circumstellar gas on the resulting polarimetric Balmer jump. The Balmer jump is a distinguishing feature of the polarization signature in these objects and, … rickie fowler house
