Archival transients detected with the MeerLICHT telescope I: Supernovae
O. Mogawana, P. J. Groot, N. Blagorodnova +9
Wide-field optical transient surveys collectively discover 50 new transients per night, making rapid, multi-filter and/or spectroscopic follow-up of all but the most exceptio…
Discovery of a radio-flaring M dwarf in a commensal transient search of the LADUMA field
Moses Mlangeni, Patrick A. Woudt, Paul J. Groot +11
We report the discovery and characterisation of MKT J032848.4-271904.6, a new radio transient identified in the LADUMA field using SARAO Science Data Processor (SDP) UHF-band image…
Hertzsprung gap stars in nearby galaxies and the Quest for Luminous Red Novae Progenitors
Hugo Tranin, Nadejda Blagorodnova, Viraj Karambelkar +5
After the main sequence phase, stars more massive than 2.5 M rapidly evolve through the Hertzsprung gap as yellow giants and supergiants (YSG), before settling into the red…
Identifying and characterising the population of hot sub-luminous stars with multi-colour MeerLICHT data
P. Ranaivomanana, C. Johnston, P. J. Groot +9
Colour-magnitude diagrams reveal a population of blue (hot) sub-luminous objects with respect to the main sequence. These hot sub-luminous stars are the result of evolutionary proc…
A spectroscopic, photometric, polarimetric and radio study of the eclipsing polar UZ Fornacis: the first simultaneous SALT and MeerKAT observations
Zwidofhelangani N. Khangale, Stephen B. Potter, Patrick A. Woudt +17
We present phase-resolved spectroscopy, photometry and circular spectropolarimetry of the eclipsing polar UZ Fornacis. Doppler tomography of the strongest emission lines using the…
