V-45(p,gamma) thermonuclear reaction rate relevant to Ti-44 production in core-collapse supernovae : General estimates and shell model analysis
(2002-07)The lack of knowledge of the V-45(p,gamma) reaction rate has been shown to contribute a large uncertainty to the production of Ti-44 in core-collapse supernovae. By considering likely contributions from resonances associated ... -
V-LoTSS: The circularly polarised LOFAR Two-metre Sky Survey
(2023-02-17)We present the detection of 68 sources from the most sensitive radio survey in circular polarisation conducted to date. We used the second data release of the 144 MHz LOFAR Two-metre Sky Survey to produce circularly polarised ... -
V346 Nor: the post-outburst life of a peculiar young eruptive star
(2020-02-03)FU Orionis-type objects (FUors) are young low-mass stars undergoing powerful accretion outbursts. The increased accretion is often accompanied by collimated jets and energetic, large-scale molecular outflows. The extra ... -
