High-precision K2/TESS Photometry and HERMES Spectroscopy of Four Bright Field Stars
Otto Trust, Santosh Joshi, Benard Nsamba +13
Space-based photometry from K2 and TESS, coupled with high-resolution spectroscopy, provides a unique opportunity to re-examine the variability and chemical nature of four bright s…
High-precision photometric and high-resolution spectroscopic characterisation of HD 180347
Otto Trust, Lyudmila Mashonkina, Edward Jurua +3
We report the analysis of high-precision space-based photometric and high-resolution spectroscopic observations of HD 180347. The high-quality light curves from the Transiting Exop…
The role of density perturbation on planet formation by pebble accretion
Geoffrey Andama, Nelson Ndugu, Simon . K. Anguma +1
Protoplanetary discs exhibit a diversity of gaps and rings of dust material, believed to be a manifestation of pressure maxima commonly associated with an ongoing planet formation…
Planetary core formation via multi-species pebble accretion
Geoffrey Andama, Nelson Ndugu, Simon Katrini Anguma +1
In the general classical picture of pebble-based core growth, planetary cores grow by accretion of single pebble species. The growing planet may reach the so-called pebble isolatio…
Study of Chemically Peculiar Stars-I : High-resolution Spectroscopy and K2 Photometry of Am Stars in the Region of M44
Santosh Joshi, Otto Trust, E. Semenko +30
We present a study based on the high-resolution spectroscopy and K2 space photometry of five chemically peculiar stars in the region of the open cluster M44. The analysis of the hi…
Rotation and spots in normal A and Am/Fm stars
Otto Trust, Edward Jurua, Peter De Cat +1
Frequency analysis of long-term ultra-precise photometry can lead to precise values of rotation frequencies of rotating stars with ``hump and spike'' features in their periodograms…
