Irradiation-Driven Formation of Supersoft X-ray Sources Following Classical Novae
Weitao Zhao, Xiangcun Meng, Yingzhen Cui +1
Supersoft X-ray sources (SSSs) are characterized by persistent thermonuclear burning on the surfaces of white dwarfs (WDs).The standard model requires high mass transfer rates of $…
The fractions of reflection effect systems detected in different subclasses of hot subdwarfs
Ruijie He, Xiangcun Meng, Zhenxin Lei
Hot subdwarfs with close low-mass M-type or brown dwarf companions usually show the reflection effect and often also eclipses. Through inspecting the light variations, we estimate…
Time-Varying Causal Survival Learning
Xiang Meng, Iavor Bojinov
This work bridges the gap between staggered adoption designs and survival analysis to estimate causal effects in settings with time-varying treatments, addressing a fundamental cha…
Harnack inequality for weakly coupled nonlocal systems
Zhen-Qing Chen, Xiangqian Meng
In this paper, we consider a weakly coupled system of nonlocal operators which contain both diffusion part with uniformly elliptic diffusion matrices and bounded drift vectors and…
