Tricouplers for nulling interferometry with photonic integrated circuits
Anusha Pai Asnodkar, Nemanja Jovanovic, Harry-Dean Kenchington Goldsmith +7
Solar System analog gas giants and habitable-zone terrestrial planets are observationally elusive to conventional exoplanet detection and characterization techniques, i.e. transits…
Technologies and novel components for broadband splitting and coupling in pairwise and nulling interferometry
Harry-Dean Kenchington Goldsmith, Nemanja Jovanovic, Anusha Pai Asnodkar +9
Passive and active photonic components are central to the continued development of astronomical photonic integrated circuits (PICs), although achieving broadband achromatic perform…
Benchmark Brown Dwarf Systems I: Chemical Abundance Analysis of FGK Stars with Wide-Separation Brown Dwarf Companions Using PEPSI
Caprice L. Phillips, Megan Bedell, Catherine Manea +11
The authors performed a high‑resolution spectroscopic survey of 32 FGK stars that host wide‑separation brown dwarf companions, deriving precise stellar parameters and abundances fo…
Tri-coupler geometries for achromatic nulling interferometry in the near-infrared
Harry-Dean Kenchington Goldsmith, Nemanja Jovanovic, Anusha Pai Asnodkar +4
Astrophotonics is central to the next generation of astronomical instrumentation, enabling compact photonic integrated circuits for both ground-based observatories and future space…
Surveying Ultra-hot Jupiters using Phase Curves with
Kaz Gary, Ji Wang, Anusha Pai Asnodkar +1
Due to their high equilibrium temperatures ( 2000 K), ultra-hot Jupiters (UHJs) are the best characterized exoplanets to date. However, many questions about their forma…
PEPSI Investigation, Retrieval, and Atlas of Numerous Giant Atmospheres (PIRANGA). II. Phase-Resolved Cross-Correlation Transmission Spectroscopy of KELT-20b
Calder Lenhart, Marshall C. Johnson, Ji Wang +5
KELT-20b is a well-studied ( K) ultra hot Jupiter, but its multidimensional atmospheric structure remains unconstrained. We performed high-resolution cross-corr…
