... Seminar archive . ... Seminar archive 2013 19 July . ... Wide-field transient surveys and supernova shock breakout . ... Many transient surveys are performed intensively in these days and time-domain astronomy comes under the spotlight. ... The shock breakout is the bolometrically brightest phenomenon in supernovae but it is difficult to observe the shock breakout due to the short duration and X-ray/ultraviolet-peaked spectra. ... All seminars: . ...

Subsystemsof RR Lyrae Variable Stars in Our Galaxy . ... Field stars displaying more rapid motion and clusters with redderh orizontal branches constitute the spheroidal subsystem of the accreted outer halo, which is approximately a factor of three larger in size than the first two subsystems. ... Both the clusters and field stars belong to at least three Galactic subsystems: the thick disk and genetically related inner proto-disk halo, and the outer accreted halo. ...
