Constraints on core-collapse supernova progenitors from explosion site integral field spectroscopy
H. Kuncarayakti, J. P. Anderson, L. Galbany +7
Observationally, supernovae (SNe) are divided into subclasses pertaining to their distinct characteristics. This diversity reflects the diversity in the progenitor stars. It is not…
Sumo Puff: Tidal Debris or Disturbed Ultra-Diffuse Galaxy?
Johnny P. Greco, Jenny E. Greene, Adrian M. Price-Whelan +10
We report the discovery of a diffuse stellar cloud with an angular extent , which we term "Sumo Puff", in data from the Hyper Suprime-Cam Subaru Strategic…
Spiral Structure and Differential Dust Size Distribution in the LkHa 330 Disk
E. Akiyama, J. Hashimoto, H. B. Liu +58
Dust trapping accelerates the coagulation of dust particles, and thus it represents an initial step toward the formation of planetesimals. We report -band (1.6 um) linear polari…
The Structure of Pre-transitional Protoplanetary Disks. II. Azimuthal Asymmetries, Different Radial Distributions of Large and Small Dust Grains in PDS~70
J. Hashimoto, T. Tsukagoshi, J. M. Brown +54
The formation scenario of a gapped disk, i.e., transitional disk, and its asymmetry is still under debate. Proposed scenarios such as disk-planet interaction, photoevaporation, gra…
Constraining supernova progenitors: an integral field spectroscopic survey of the explosion sites
H. Kuncarayakti, G. Aldering, J. P. Anderson +9
We describe a survey of nearby core-collapse supernova (SN) explosion sites using integral field spectroscopy (IFS) technique, which is an extension of the work described in Kuncar…
Kinematics of Ionized Gas at 0.01 AU of TW Hya
M. Goto, A. Carmona, H. Linz +4
We report two-dimensional spectroastrometry of Br gamma emission of TW Hya to study the kinematics of the ionized gas in the star-disk interface region. The spectroastrometry with…
