SALT observations of the Chromospheric Activity of Transiting Planet Hosts: Mass Loss and Star Planet Interactions
D. Staab, C. A. Haswell, Gareth D. Smith +4
We measured the chromospheric activity of the four hot Jupiter hosts WASP-43, WASP-51/HAT-P-30, WASP-72 & WASP-103 to search for anomalous values caused by the close-in companions.…
Recovering planet radial velocity signals in the presence of starspot activity in fully convective stars
J. R. Barnes, S. V. Jeffers, G. Anglada-Escude +6
Accounting for stellar activity is a crucial component of the search for ever-smaller planets orbiting stars of all spectral types. We use Doppler imaging methods to demonstrate th…
Pulsation versus metallicism in Am stars as revealed by LAMOST and WASP
B. Smalley, V. Antoci, D. L. Holdsworth +13
We present the results of a study of a large sample of A and Am stars with spectral types from LAMOST and light curves from WASP. We find that, unlike normal A stars, Sct pulsa…
Variable stars in the bulge globular cluster NGC 6401
Y. Tsapras, A. Arellano Ferro, D. M. Bramich +7
We present a study of variable stars in globular cluster NGC 6401. The cluster is only $5.3\degr$ away from the Galactic centre and suffers from strong differential reddening. The…
The ALMA detection of CO rotational line emission in AGB stars in the Large Magellanic Cloud
M. A. T. Groenewegen, W. H. T. Vlemmings, P. Marigo +21
Context: Low- and intermediate-mass stars lose most of their stellar mass at the end of their lives on the asymptotic giant branch (AGB). Determining gas and dust mass-loss rates (…
ALMA observations of the supergiant B[e] star Wd1-9
D. Fenech, J. S. Clark, R. K. Prinja +3
Mass-loss in massive stars plays a critical role in their evolution, although the precise mechanism(s) responsible - radiatively driven winds, impulsive ejection and/or binary inte…
