LRG-BEASTS: Ground-based Detection of Sodium and a Steep Optical Slope in the Atmosphere of the Highly Inflated Hot-Saturn WASP-21b

L. Alderson, J. Kirk, M. López-Morales +7

We present the optical transmission spectrum of the highly inflated Saturn-mass exoplanet WASP-21b, using three transits obtained with the ACAM instrument on the William Herschel T…

Hubble PanCET: An isothermal day-side atmosphere for the bloated gas-giant HAT-P-32Ab

N. Nikolov, D. K. Sing, J. Goyal +20

We present a thermal emission spectrum of the bloated hot Jupiter HAT-P-32Ab from a single eclipse observation made in spatial scan mode with the Wide Field Camera 3 (WFC3) aboard…

First Images of Cool Starspots on a Star Other than the Sun: Interferometric Imaging of Andromedae

J. R. Parks, R. J. White, F. Baron +14

Presented are the first interferometric images of cool starspots on the chromospherically active giant Andromedae. These images represent the first model-independent images of…

Ap stars with variable periods

Zdeněk Mikulášek, Jiří Krtička, Jan Janík +5

The majority of magnetic chemically peculiar (mCP) stars exhibit periodic light, magnetic, radio, and spectroscopic variations that can be adequately modelled as a rigidly-rotating…

HR 7355 - another rapidly braking He-strong CP star?

Z. Mikulasek, J. Krticka, G. W. Henry +3

Strong meridional mixing induced by rapid rotation is one reason why all hot main-sequence stars are not chemically peculiar. However, the finding that the He-strong CP star HR 735…

The nature of the light variability of the silicon star HR 7224

J. Krticka, Z. Mikulasek, G. W. Henry +4

Although photometric variations of chemically peculiar (CP) stars are frequently used to determine their rotational periods, the detailed mechanism of their light variability remai…
