摘要:

我们目前的结果,从六年的重新校准和新的光谱偏振数据与威斯康星大学的半波光谱偏振仪(HPOL)和六年的新数据与光弹调制偏振仪(PEMP)在花和库克天文台。将这些数据与文献中的偏振数据相结合,使我们能够表征固有的BVRI偏振光曲线。在总光变曲线和V波段偏振曲线的次极小值之间存在0.245天(约6小时)的可重复差异,在其他波段也有类似的行为,这可能是盘边缘吸积热点的第一个直接证据。

英文摘要:

We present results from six years of recalibrated and new spectropolarimetric data taken with the University of Wisconsin's Half-Wave Spectropolarimeter (HPOL) and six years of new data taken with the photoelastic modulating polarimeter (PEMP) at the Flower and Cook Observatory. Combining these data with polarimetric data from the literature allows us to characterize the intrinsic BVRI polarized light curves. A repeatable discrepancy of 0.245 days (approximately 6 hours) between the secondary minima in the total light curve and the polarization curve in the V band, with similar behavior in the other bands, may represent the first direct evidence for an accretion hot spot on the disk edge.
