What's Behind the Elephant's Trunk? Identifying Young Stellar Objects on the Outskirts of IC1396
Steven M. Silverberg, Hans Moritz Guenther, Jinyoung Serena Kim +2
Empirically, the estimated lifetime of a typical protoplanetary disk is Myr. However, the disk lifetimes required to produce a variety of observed exoplanetary systems may…
UV Fluorescence Traces Gas and LyA Evolution in Protoplanetary Disks
Nicole Arulanantham, Kevin France, Keri Hoadley +5
Ultraviolet spectra of protoplanetary disks trace distributions of warm gas at radii where rocky planets form. We combine HST-COS observations of H2 and CO emission from 12 classic…
How to organize an online conference -- Lessons learned from Cool Stars 20.5 (virtually cool)
Hans Moritz Günther, James R. A. Davenport, Scott Wolk +1
The virtual meeting was a success. Several people told us that this was "the best virtual meeting they had seen so far", which, a year into the pandemic and without a commercial pr…
PENELLOPE: the ESO data legacy program to complement the Hubble UV Legacy Library of Young Stars (ULLYSES) I. Survey presentation and accretion properties of Orion OB1 and -Orionis
C. F. Manara, A. Frasca, L. Venuti +69
The evolution of young stars and disks is driven by the interplay of several processes, notably accretion and ejection of material. Critical to correctly describe the conditions of…
The auto and cross angular power spectrum of the Cas A supernova remnant in radio and X-ray
Preetha Saha, Somnath Bharadwaj, Susmita Chakravorty +4
The shell type supernova remnant (SNR) Cas A exhibits structures at nearly all angular scales. Previous studies show the angular power spectrum of the radio emission t…
Change point detection and image segmentation for time series of astrophysical images
Cong Xu, Hans Moritz Günther, Vinay L. Kashyap +2
Many astrophysical phenomena are time-varying, in the sense that their intensity, energy spectrum, and/or the spatial distribution of the emission suddenly change. This paper devel…
