Near-Earth Supernova Explosions: Evidence, Implications, and Opportunities
Brian D. Fields, John R. Ellis, Walter R. Binns +36
There is now solid experimental evidence of at least one supernova explosion within 100 pc of Earth within the last few million years, from measurements of the short-lived isotope…
Discovery of a directly imaged disk in scattered light around the Sco-Cen member Wray 15-788
A. J. Bohn, M. A. Kenworthy, C. Ginski +10
As part of our on-going survey we have carried out high-contrast imaging with VLT/SPHERE/IRDIS to obtain polarized and total intensity images of the young (Myr old)…
DECam Survey for Low-Mass Stars and Substellar Objects in the UCL and LCC Subgroups of the Sco-Cen OB Association (SCOCENSUS)
Fred E. Moolekamp, Eric E. Mamajek, David J. James +5
Using images taken with the Dark Energy Camera (DECam), the first extensive survey of low mass and substellar objects is made in the 15-20 Myr Upper Centaurus Lupus (UCL) and Lower…
Supernova Ejecta in Ocean Cores Used as Time Constraints for Nearby Stellar Groups
Megan Hyde, Mark J. Pecaut
Evidence of a supernova event, discussed in Wallner et al., was discovered in the deep-sea crusts with two signals dating back to 2-3 and 7-9 Myr ago. In this contribution, we plac…
Angular Momentum Evolution of Young Stars in the Nearby Scorpius-Centaurus OB Association
Samuel N. Mellon, Eric E. Mamajek, Thomas E. Oberst +1
We report the results of a study of archival SuperWASP light curves for stars in Scorpius-Centaurus (Sco-Cen), the nearest OB association. We use SuperWASP time-series photometry t…
Anomalous Spectral Types and Intrinsic Colors of Young Stars
Mark J. Pecaut
We highlight differences in spectral types and intrinsic colors observed in pre-main sequence (pre-MS) stars. Spectral types of pre-MS stars are wavelength-dependent, with near-inf…
