The Large Area Proportional Counter (LAXPC) instruments onboard the AstroSat Observatory has observed the X-ray binary system Her X-1 during AstroSAT observing sessions AO2, AO3 and TO2. These include observations while Her X-1 is in different stages of its 35 day cycle: Low State, Turn-On to Main High State, peak of Main High State and early decline of Main High State. These observations also include a number of dips and one egress of neutron star eclipse. Here we present light curves and softness ratio analysis for these observations and discuss new features of the spectral changes with 35-day phase and orbital phase. We find a new phenomenon for dips during Main High State: about half of the dips show constant softness ratio as count rate decreases, which has not been seen before, and could be caused by highly ionized matter or very dense cold matter. The other half of the dips show the normal decrease of softness ratio as count rate decreases. These are caused by cold matter absorption and were previously known.

AstroSat 天文台上的大面积比例计数器 (LAXPC) 仪器在 AstroSAT 观测会议 AO2、AO3 和 TO2 期间观测了 X 射线双星系统 Her X-1。其中包括当 Her X-1 处于其 35 天周期的不同阶段时的观察：低状态、开启至主要高状态、主要高状态的峰值和主要高状态的早期下降。这些观测还包括中子星日食的多次下降和一次出口。在这里，我们对这些观察结果进行了光变曲线和软度比分析，并讨论了 35 天相位和轨道相位的光谱变化的新特征。我们在 Main High State 期间发现了一个新的倾角现象：随着计数率的降低，大约一半的倾角显示出恒定的柔软度，这是以前从未见过的，并且可能由高度电离的物质或非常致密的冷物质引起。另一半下降显示柔软度随计数率降低而正常降低。这些是由冷物质吸收引起的，以前是已知的。
