Motivated by recent work on rotating black hole shadow (Chang and Zhu in Phys Rev D 101:084029, 2020), we investigate the shadow behaviours of rotating Hayward–de Sitter black hole for static observers at a finite distance in terms of astronomical observables. This paper uses the newly introduced distortion parameter (Chang and Zhu in Phys Rev D 102:044012, 2020) to describe the shadow’s shape quantitatively. We show that the spin parameter would distort shadows and the magnetic monopole charge would increase the degree of deformation. The distortion will increase as the distance between the observer and the black hole increases, and distortion reduces as the cosmological constant increases. Besides, the increase of the spin parameter, magnetic monopole charge and cosmological constant will cause the shadows shrunken.

受近期关于旋转黑洞阴影的研究的启发（Chang和Zhu在Phys Rev D 101：084029，2020中），我们从天文观测资料的角度研究了在有限距离内为静态观测者旋转的Hayward-de Sitter黑洞的阴影行为。本文使用新引入的畸变参数（Phys Rev D 102：044012，2020年的Chang和Zhu）定量描述阴影的形状。我们表明，自旋参数将使阴影变形，并且磁单极电荷将增加变形程度。扭曲将随着观察者与黑洞之间距离的增加而增加，并且扭曲随着宇宙常数的增加而减小。此外，自旋参数，磁单极电荷和宇宙常数的增加会导致阴影缩小。
