Modeling photometric variations due to a global inhomogeneity on an obliquely rotating star: application to lightcurves of white dwarfs

Yasushi Suto, Shin Sasaki, Masataka Aizawa +2

We develop a general framework to compute photometric variations induced by the oblique rotation of a star with an axisymmetric inhomogeneous surface. We apply the framework to com…

Analytic model for photometric variation due to starspots on a differentially rotating star

Yasushi Suto, Shin Sasaki, Yuta Nakagawa +1

We present an analytic model of the lightcurve variation for stars with non-evolving starspots on a differentially rotating surface. The Fourier coefficients of the harmonics of th…

Disentangling the stellar inclination of transiting planetary systems: fully analytic approach to the Rossiter-McLaughlin effect incorporating the stellar differential rotation

Shin Sasaki, Yasushi Suto

The Rossiter-McLaughlin (RM) effect has been widely used to estimate the sky-projected spin-orbit angle, , of transiting planetary systems. Most of the previous analysis assume…

Shapes and alignments of dark matter haloes and their brightest cluster galaxies in 39 strong lensing clusters

Taizo Okabe, Masamune Oguri, Sébastien Peirani +6

We study shapes and alignments of 45 dark matter (DM) haloes and their brightest cluster galaxies (BCGs) using a sample of 39 massive clusters from Hubble Frontier Field (HFF), Clu…

Cosmological evolution of orientations of cluster-sized dark matter haloes and their central galaxies in the Horizon-AGN simulation

Taizo Okabe, Takahiro Nishimichi, Masamune Oguri +6

It is known observationally that the major axes of galaxy clusters and their brightest cluster galaxies are roughly aligned with each other. To understand the origin of the alignme…

High entropy and evidence for a merger in the low surface brightness cluster Abell 2399

Ikuyuki Mitsuishi, Yasunori Babazaki, Naomi Ota +4

We present results of the X-ray analyses of the nearby cluster of galaxies Abell 2399 () using the XMM-Newton and Suzaku satellites. This cluster is classified as a low su…
