No escaping helium from 55 Cnc e
Michael Zhang, Heather A. Knutson, Lile Wang +3
We search for escaping helium from the hot super Earth 55 Cnc e by taking high-resolution spectra of the 1083 nm line during two transits using Keck/NIRSPEC. We detect no helium ab…
PLATON II: New Capabilities And A Comprehensive Retrieval on HD 189733b Transit and Eclipse Data
Michael Zhang, Yayaati Chachan, Eliza M. -R. Kempton +3
Recently, we introduced PLanetary Atmospheric Tool for Observer Noobs (PLATON), a Python package that calculates model transmission spectra for exoplanets and retrieves atmospheric…
The Orbit of WASP-12b is Decaying
Samuel W. Yee, Joshua N. Winn, Heather A. Knutson +6
WASP-12b is a transiting hot Jupiter on a 1.09-day orbit around a late-F star. Since the planet's discovery in 2008, the time interval between transits has been decreasing by $29\p…
A Hubble PanCET Study of HAT-P-11b: A Cloudy Neptune with a Low Atmospheric Metallicity
Yayaati Chachan, Heather A. Knutson, Peter Gao +14
We present the first comprehensive look at the m transmission spectrum of the warm ( K) Neptune HAT-P-11b derived from thirteen individual transits observed u…
Mass Loss from the Exoplanet WASP-12b Inferred from Phase Curves
Taylor J. Bell, Michael Zhang, Patricio E. Cubillos +12
The exoplanet WASP-12b is the prototype for the emerging class of ultra-hot, Jupiter-mass exoplanets. Past models have predicted---and near ultra-violet observations have shown---t…
Modules for Experiments in Stellar Astrophysics (MESA): Pulsating Variable Stars, Rotation, Convective Boundaries, and Energy Conservation
Bill Paxton, R. Smolec, Josiah Schwab +14
We update the capabilities of the open-knowledge software instrument Modules for Experiments in Stellar Astrophysics (MESA). RSP is a new functionality in MESAstar that models the…
