Insight-
HXMT started the scientific observation since June 22nd, 2017.
And now it has lasted for 168 days.
In these days, we have made 73 normal plans and 9 ToO plans.
27 sources have been observed for 204 times.
The Crab area has been scanned for 9 times, and the 21 regions in Galactic plane has been scanned for 192 times.
This information is available on the website:
Some scientific results of these observations has been derived, and which also will be reported following.

12. MAXI/BAT light curves and HXMT snapshots

17. Thank you !

18. Accretion via both the inner Lagrange point and stellar wind

19. Wind velocity can be inferred from the orbital X-ray profile

20. Intense X-ray variability of Vela X-1, lasting from a few minutes to several hours, is commonly thought to be associated with changes in the accretion rate and to inhomogeneities in the stellar wind flow. There have been reports, on the one hand, of reductions in the flux to less than 10% of its normal emission (“off states”), as well as of very active states, on the other, with increases in the flux by sometimes more than a factor of.

21. CygX-3是一个持续亮的HMXB系统，有4
CygX-3是一个持续亮的HMXB系统，有4.8小时轨道周期，以及34天吸积盘进动的超轨周期，HXMT监测了其在2017年的爆发。该系统具有丰富的时变（QPO）和能谱态，虽然其致密星性质尚不确定，但从辐射特征上看，可能是BH，该源具有伽玛辐射，2015年的爆发Astrosat做了报道。基于这些特性，特别是，可能是一个BH的具有伽玛辐射的HMXB，使得这个系统非常有特色，
