GW170817 is the first detected gravitational wave source from a neutron star merger. We
present the Japanese collaboration for gravitational-wave electro-magnetic (J-GEM) follow …

We present the first measurement of the mass function of free-floating planets (FFPs), or very
wide orbit planets down to an Earth mass, from the MOA-II microlensing survey in 2006 …

We present a detailed elemental abundance study of 90 F and G dwarf, turn-off, and
subgiant stars in the Galactic bulge. Based on high-resolution spectra acquired during …

At least 30% of main sequence stars host planets with sizes of between 1 and 4 Earth radii
and orbital periods of less than 100 days. We use N-body simulations including a model for …

We report the discoveries of low-mass free-floating planet (FFP) candidates from the
analysis of 2006–2014 MOA-II Galactic bulge survey data. In this data set, we found 6111 …

Exoplanet surveys have confirmed one of humanity's (and all teenagers') worst fears: We are
weird. If our solar system were observed with present-day Earth technology—to put our …

We present the analyses of two microlensing events, OGLE-2018-BLG-0567 and OGLE-
2018-BLG-0962. In both events, the short-lasting anomalies were densely and continuously …
