Hard X-ray and Infrared Emission from Apparently Single White Dwarfs
Y. -H. Chu, R. A. Gruendl, M. A. Guerrero +1
The photospheric emission of a white dwarf (WD) is not expected to be detectable in hard X-rays or the mid-IR. Hard X-ray (~1 keV) emission associated with a WD is usually attribut…
Faint companions in the close environment of star-forming dwarf galaxies: possible overlooked starburst triggers?
K. G. Noeske, J. Iglesias-Paramo, J. M. Vilchez +2
Using the NASA Extragalactic Database, we have searched the close environment of 98 star-forming dwarf galaxies (SFDGs) from field- and low density environments for companion galax…
Optical & NIR photometry of the interacting Dwarf Galaxies II Zw 70/II Zw 71
P. Papaderos, K. G. Noeske, L. M. Cairos +2
We obtained deep optical and NIR images of the pair of blue compact dwarf (BCD) galaxies II Zw 70 and II Zw 71 in order to study the effects of interaction on the structural proper…
The survival of 205Pb in intermediate-mass AGB stars
Nami Mowlavi, Stephane Goriely, Marcel Arnould
The now extinct 205Pb is a pure s-process radionuclide (t_{1/2} = 1.5x10^7 y) of possible substantial cosmochemical interest. As a necessary complement to the detailed theoretical…
