We are grateful to Atsushi Naruko for organizing a workshop “Essential next steps for gravity and cosmology” held at FRIS, Tohoku University, where we came up with the idea for this Letter. We would like to thank Pierre Fleury, Hajime Fukushima, Mikhail M. Ivanov, Dmitry Levkov, Takahiro Tanaka, Jun Hashimoto, Daisuke Toyouchi, Sergey Troitsky, and Ken’ichi Saikawa for useful discussions and comments. This work is partially supported by the Grants-in-Aid for JSPS Research Fellow No. 17J09103 (T. F.) and No. 17J02411 (R. T.), and by JSPS Grants-in-Aid for Scientific Research 18H01245 (K. T.).

N2 - We find that the polarimetric observations of protoplanetary disks are useful to search for ultralight axion dark matter. Axion dark matter predicts the rotation of the linear polarization plane of propagating light, and protoplanetary disks are ideal targets to observe it. We show that a recent observation puts the tightest constraint on the axion-photon coupling constant for an axion mass m 10-21 eV.
