The Pictoris b Hill sphere transit campaign. Paper II: Searching for the signatures of the Pictoris exoplanets through time delay analysis of the Scuti pulsations
Sebastian Zieba, Konstanze Zwintz, Matthew Kenworthy +34
The Pictoris system is the closest known stellar system with directly detected gas giant planets, an edge-on circumstellar disc, and evidence of falling sublimating bodies and…
The Pictoris b Hill sphere transit campaign. Paper I: Photometric limits to dust and rings
M. A. Kenworthy, S. N. Mellon, J. I. Bailey +33
Photometric monitoring of Beta Pictoris in 1981 showed anomalous fluctuations of up to 4% over several days, consistent with foreground material transiting the stellar disk. The su…
Arid or Cloudy: Characterizing the Atmosphere of the super-Earth 55 Cancri e using High-Resolution Spectroscopy
Abhinav Jindal, Ernst J. W. de Mooij, Ray Jayawardhana +6
The nearby super-Earth 55 Cnc e orbits a bright (V = 5.95 mag) star with a period of ~ 18 hours and a mass of ~ 8 Earth masses. Its atmosphere may be water-rich and have a large sc…
Search for TiO and Optical Night-side Emission from the Exoplanet WASP-33b
Miranda K. Herman, Ernst J. W. de Mooij, Ray Jayawardhana +1
With a temperature akin to an M-dwarf, WASP-33b is among the hottest Jupiters known, making it an ideal target for high-resolution optical spectroscopy. By analyzing both transmiss…
Coherent radio emission from a quiescent red dwarf indicative of star-planet interaction
H. K. Vedantham, J. R. Callingham, T. W. Shimwell +11
Low frequency (MHz) stellar radio emission is expected to originate in the outer corona at heights comparable to and larger than the stellar radius. Such emission…
Detection of ionized calcium in the atmosphere of the ultra-hot Jupiter KELT-9b
Jake D. Turner, Ernst J. W. de Mooij, Ray Jayawardhana +6
With a day-side temperature in excess of 4500K, comparable to a mid-K-type star, KELT-9b is the hottest planet known. Its extreme temperature makes KELT-9b a particularly interesti…
