TL;DR: In this paper, the results of an extensive, multi-observatory campaign designed to probe for spectral and/or rotational changes to Duende due to gravitational interactions with the Earth during the flyby were presented.

TL;DR: In this paper, the authors derived the continuum polarization degree of 2P/Encke using the Cassegrain focus of the 150-cm Kanata telescope on UT 2017 February 21 when the comet was at the solar phase angle of 75.7 deg.

TL;DR: In this paper, the AKARI mid-IR all-sky point source catalog (PSC) was used to explore debris disks using the IR excess emission for 678 isolated main-sequence stars by comparing their fluxes with the predicted fluxes of the photospheres based on optical to near-IR fluxes and model spectra.

TL;DR: In this paper, the authors report observations of the Type Iax supernova 2012Z at optical and near-infrared wavelengths from immediately after the explosion until approximately 260 days after the maximum luminosity using the Optical and Infrared Synergetic Telescopes for Education and Research (OISTER) Target-of-Opportunity (ToO) program and the Subaru telescope.

TL;DR: In this article, the authors examined the annual parallax measurement and conducted K'-band photometric monitoring of an SRV star SV Pegasus (SV Peg) in the Large Magellanic Cloud (LMC).
