论文摘要
本文列出了近红外光度观察的近红外光度观测结果。使用Nishi-Harima天文天文台,日本和Nishi-Harima红外摄像头(NIC)的Nayuta 2 M望远镜(NIC)进行精确的近红外光度法。在196分钟内,在每个乐队中拍摄了170 J-,H-和KS波段图像。观察到行星系统的通量在运输事件期间减少。虽然KS波段的Transit深度与R波段相似,但J-和H波段的转移比KS波段中的Transit更深。我们构建了行星气氛的简单模型,发现观察到的过境深度通过含有H2S分子的充气大气很好地再现。
The results of near-infrared photometric observations of a transit event of an extrasolar planet HAT-P-54b are presented herein. Precise near-infrared photometry was carried out using the Nayuta 2 m telescope at Nishi-Harima Astronomical Observatory, Japan and Nishi-harima Infrared Camera (NIC). 170 J-, H-, and Ks-band images were taken in each band in 196 minutes. The flux of the planetary system was observed to decrease during the transit event. While the the Ks-band transit depth is similar to that in the r-band, the J- and H-band transits are deeper than those in the Ks-band. We constructed simple models of the planetary atmosphere and found that the observed transit depths are well reproduced by inflated atmosphere containing H2S molecule.
