Demographics of Close-In TESS Exoplanets Orbiting FGK Main-sequence Stars

Kaiming Cui, David J. Armstrong, Andreas Hadjigeorghiou +5

Understanding the demographics of close-in planets is crucial for insights into exoplanet formation and evolution. We present a detailed analysis of occurrence rates for close-in (…

Resolving star spots on WASP-85 A using high-resolution transit spectroscopy

Vedad Kunovac, Heather Cegla, Hritam Chakraborty +23

Stellar surface inhomogeneities such as spots and faculae introduce Doppler variations that challenge exoplanet detection via the radial velocity method. While their impact on disc…

Astroclimes -- measuring the abundance of CO and CH in the Earth's atmosphere using astronomical observations

Marcelo Aron Fetzner Keniger, David Armstrong, Matteo Brogi +2

Monitoring the abundance of greenhouse gases (GHGs) such as carbon dioxide (CO) and methane (CH) is necessary to quantify their impact on global warming and climate change.…

Exploring the Neptunian Desert: Insights from a Homogeneous Planetary Sample

Lauren Doyle, David J. Armstrong, Lorena Acuña +26

In this paper, we present a homogeneous analysis of close-in Neptune planets. To do this, we compile a sample of TESS-observed planets using a ranking criterion which takes into ac…

Detectability of oxygen fugacity regimes in the magma ocean world 55 Cancri e at high spectral resolution

Spandan Dash, Matteo Brogi, Fabian Lukas Seidler +5

Ultra-short Period exoplanets (USPs) like 55 Cnc e, hosting dayside magma oceans, present unique opportunities to study surface-atmosphere interactions. The composition of a vapori…
