From the bulge to the outer disc: StarHorse stellar parameters, distances, and extinctions for stars in APOGEE DR16 and other spectroscopic surveys
A. B. A. Queiroz, F. Anders, C. Chiappini +27
We combine high-resolution spectroscopic data from APOGEE-2 Survey Data Release 16 (DR16) with broad-band photometric data from several sources, as well as parallaxes from {\it Gai…
The infrared properties of the new outburst star IRAS 05436-0007 in quiescent phase
P. Ãbrahám, Ã. Kóspál, Sz. Csizmadia +3
We compiled and investigated the infrared/sub-mm/mm SED of the new outburst star IRAS 05436-0007 in quiescent phase. The star is a flat-spectrum source, with an estimated total lum…
Stellar population models based on the SDSS-IV MaStar library of stellar spectra. I. Intermediate-age/old models
C. Maraston, L. Hill, D. Thomas +14
We use the first release of the SDSS/MaStar stellar library comprising ~9000, high S/N spectra, to calculate integrated spectra of stellar population models. The models extend over…
Achieving Transformative Understanding of Extreme Stellar Explosions with ELT-enabled Late-time Spectroscopy
D. Milisavljevic, R. Margutti, R. Chornock +35
Supernovae are among the most powerful and influential explosions in the universe. They are also ideal multi-messenger laboratories to study extreme astrophysics. However, many fun…
X-Ray Spectral Variability During an Outburst in V1118 Ori
M. Audard, M. Guedel, S. L. Skinner +5
We present results from a multi-wavelength campaign to monitor the 2005 outburst of the low-mass young star V1118 Ori. Although our campaign covers the X-ray, optical, infrared, an…
A panchromatic view of the restless SN2009ip reveals the explosive ejection of a massive star envelope
R. Margutti, D. Milisavljevic, A. M. Soderberg +54
The 2012 explosion of SN2009ip raises questions about our understanding of the late stages of massive star evolution. Here we present a comprehensive study of SN2009ip during its r…
Clustering Properties of Far-Infrared Sources in Hi-GAL Science Demonstration Phase Fields
N. Billot, E. Schisano, M. Pestalozzi +9
We use a Minimum Spanning Tree algorithm to characterize the spatial distribution of Galactic Far-IR sources and derive their clustering properties. We aim to reveal the spatial im…
