XUV Radiation from A-stars: Implications for Ultra-hot Jupiters
L. Fossati, T. Koskinen, J. D. Lothringer +3
Extremely irradiated, close-in planets to early-type stars might be prone to strong atmospheric escape. We review the literature showing that X-ray-to-optical measurements indicate…
Characterisation of the HD 219134 multi-planet system I. Observations of stellar magnetism, wind, and high-energy flux
C. P. Folsom, L. Fossati, B. E. Wood +9
HD 219134 hosts several planets, with seven candidates reported, and the two shortest period planets are rocky (4-5 ) and transit the star. Here we present contemporane…
Characterisation of the HD219134 multi-planet system II. Stellar-wind sputtered exospheres in rocky planets b & c
A. A. Vidotto, H. Lichtenegger, L. Fossati +6
We present a 3D study of the formation of refractory-rich exospheres around the rocky planets HD219134b and c. These exospheres are formed by surface particles that have been sputt…
Design and modeling of a tunable spatial heterodyne spectrometer for emission line studies
Nirmal Kaipachery, Sridharan Rengaswamy, Sripadmanaban Sriram +6
Spatial Heterodyne Spectroscopy (SHS) is a relatively novel interferometric technique similar to the Fourier transform spectroscopy with heritage from the Michelson Interferometer.…
Wide-field Ultraviolet Imager for Astronomical Transient Studies
Joice Mathew, S. Ambily, Ajin Prakash +6
Though the ultraviolet (UV) domain plays a vital role in the studies of astronomical transient events, the UV time-domain sky remains largely unexplored. We have designed a wide-fi…
