Demonstration of a Single-Laser-Diode-Pumped Ti:Sapphire Astrocomb on the Southern African Large Telescope
Ewan Allan, Yuk Shan Cheng, Kamalesh Dadi +13
Astrocombs -- broadband lasers comprising thousands of narrow, uniformly spaced and atomically-referenced spectral lines -- offer gold-standard wavelength calibration for ground-ba…
Commissioning and on-sky performance of FiberPol: a fiber-fed spectropolarimetric system for the SAAO 1.9 m telescope
Siddharth Maharana, K. C. J. Dennison-Farrar, Sabyasachi Chattopadhyay +8
At the South African Astronomical Observatory (SAAO), we have developed FiberPol a spectropolarimetric front-end for the SpUpNIC spectrograph on the 1.9 m telescope fed by fiber…
Chemical abundances and doppler imaging of the Ap Si/He-wk star HD 100357
Athul Dileep, Santosh Joshi, Sofya Alexeeva +11
We present the results of time-resolved photometry, abundance analysis and Doppler imaging of an Ap star, HD 100357. The {\it TESS} photometry revealed rotational modulation with a…
Giants Transiting Giants I: A Non-inflated Hot Jupiter Orbiting a Massive Subgiant
Nicholas Saunders, Samuel K. Grunblatt, Daniel Huber +27
While the population of confirmed exoplanets continues to grow, the sample of confirmed transiting planets around evolved stars is still limited. We present the discovery and confi…
The spin rates of O stars in WR + O Magellanic Cloud binaries
Michael M. Shara, Steven M. Crawford, Dany Vanbeveren +3
Some massive, merging black holes (BH) may be descendants of binary O stars. The evolution and mass transfer between these O stars determines the spins of their progeny BH. These w…
A high-mass Planetary Nebula in a Galactic Open Cluster
Vasiliki Fragkou, Quentin Parker, Albert Zijlstra +2
Planetary Nebulae are the ionised ejected envelopes surrounding the remnant cores of dying stars. Theory predicts that main-sequence stars with one to about eight times the mass of…
