Infrared spectral signatures of light r-process elements in kilonovae
Anders Jerkstrand, Quentin Pognan, Smaranika Banerjee +8
A central question regarding neutron star mergers is whether they are able to produce all the r-process elements, from first to third peak. The high abundances of first-peak elemen…
Runaway BN supergiant star HD 93840: Progenitor of an imminent core-collapse supernova above the Galactic plane
D. Weßmayer, M. A. Urbaneja, K. Butler +1
We present a quantitative spectral analysis of the extreme nitrogen-enhanced supergiant HD 93840 (BN1 Ib) at an intermediate galactic latitude. Based on an optical high-resolution…
CRIRES high-resolution near-infrared spectroscopy of diffuse interstellar band profiles. Detection of 12 new DIBs in the YJ band and the introduction of a combined ISM sight line and stellar analysis approach
A. Ebenbichler, A. Postel, N. Przybilla +7
A high spectral resolution investigation of diffuse interstellar bands (DIBs) in the near-infrared ( band) is conducted to test new methods, to confirm and improve existing par…
Observations of the extreme runaway HD271791: nucleosynthesis in a core-collapse supernova
V. Schaffenroth, N. Przybilla, K. Butler +2
Some young, massive stars can be found in the Galactic halo. As star formation is unlikely to occur in the halo, they must have been formed in the disk and been ejected shortly aft…
HD 271791: An Extreme Supernova Runaway B Star Escaping from the Galaxy
Norbert Przybilla, Maria-Fernanda Nieva, Ulrich Heber +1
Hyper-velocity stars (HVSs) were first predicted by theory to be the result of the tidal disruption of a binary system by a super-massive black hole (SMBH) that accelerates one com…
LMC origin of the hyper-velocity star HE 0437-5439. Beyond the supermassive black hole paradigm
N. Przybilla, M. F. Nieva, U. Heber +4
Context: Hyper-velocity stars move so fast that only a supermassive black hole (SMBH) seems to be capable to accelerate them. Hence the Galactic centre (GC) is their only suggested…
