Asymmetries and Circumstellar Interaction in the Type II SN 2024bch
Jennifer E. Andrews, Manisha Shrestha, K. Azalee Bostroem +29
We present a comprehensive multi-epoch photometric and spectroscopic study of SN 2024bch, a nearby (19.9 Mpc) Type II supernova (SN) with prominent early high ionization emission l…
PEPSI's non-detection of escaping hydrogen and metal lines adds to the enigma of WASP-12 b
Anusha Pai Asnodkar, Ji Wang, Madelyn Broome +5
WASP-12 b is an ultra-hot Jupiter (UHJ) of special interest for atmospheric studies since it is on an inspiraling orbit in an extreme environment of intense radiation and circumste…
Precise and Accurate Mass and Radius Measurements of Fifteen Galactic Red Giants in Detached Eclipsing Binaries
D. M. Rowan, K. Z. Stanek, C. S. Kochanek +9
Precise and accurate mass and radius measurements of evolved stars are crucial to calibrating stellar models. Stars in detached eclipsing binaries (EBs) are excellent potential cal…
The instrumentation program at the Large Binocular Telescope Observatory in 2024
Joseph C. Shields, Jason Chu, Albert Conrad +17
The Large Binocular Telescope, with its expansive collecting area, angular resolving power, and advanced optical design, provides a robust platform for development and operation of…
PEPSI Investigation, Retrieval, and Atlas of Numerous Giant Atmospheres (PIRANGA). I. The Ubiquity of Fe I Emission and Inversions in Ultra Hot Jupiter Atmospheres
Sydney Petz, Marshall C. Johnson, Anusha Pai Asnodkar +4
We present high-resolution optical emission spectroscopy observations of the ultra hot Jupiters (UHJs) TOI-1431 b and TOI-1518 b using the PEPSI spectrograph on the LBT. We detect…
Retrieving Young Cloudy L-Dwarfs: A Nearby Planetary-Mass Companion BD+60 1417B and Its Isolated Red Twin W0047
Caprice L. Phillips, Jacqueline K. Faherty, Ben Burningham +11
We present an atmospheric retrieval analysis on a set of young, cloudy, red L-dwarfs -- CWISER J124332.12+600126.2 and WISEP J004701.06+680352.1 -- using the \textit{Brewster} retr…
Exploring the directly imaged HD 1160 system through spectroscopic characterization and high-cadence variability monitoring
Ben J. Sutlieff, Jayne L. Birkby, Jordan M. Stone +15
The time variability and spectra of directly imaged companions provide insight into their physical properties and atmospheric dynamics. We present follow-up R~40 spectrophotometric…
A population of neutron star candidates in wide orbits from Gaia astrometry
Kareem El-Badry, Hans-Walter Rix, David W. Latham +10
We report discovery and spectroscopic follow-up of 21 astrometric binaries containing solar-type stars and dark companions with masses near 1.4 . The simplest interpreta…
The PEPSI Exoplanet Transit Survey (PETS). V: New Na D transmission spectra indicate a quieter atmosphere on HD 189733b
E. Keles, S. Czesla, K. Poppenhaeger +23
Absorption lines from exoplanet atmospheres observed in transmission allow us to study atmospheric characteristics such as winds. We present a new high-resolution transit time-seri…
A neutron star candidate in a 2-year orbit
Kareem El-Badry, Joshua D. Simon, Henrique Reggiani +10
We report discovery and characterization of a main-sequence G star orbiting a dark object with mass . The system was discovered via Gaia astrometry and has…
A Walk on the Retrograde Side (WRS) project. I. Tidying-up the retrograde halo with high-resolution spectroscopy
E. Ceccarelli, D. Massari, A. Mucciarelli +7
Relics of ancient accretion events experienced by the Milky Way are predominantly located within the stellar halo of our Galaxy. However, debris from different objects display over…
Weakened Magnetic Braking in the Exoplanet Host Star 51 Peg
Travis S. Metcalfe, Klaus G. Strassmeier, Ilya V. Ilyin +11
The consistently low activity level of the old solar analog 51 Peg not only facilitated the discovery of the first hot Jupiter, but also led to the suggestion that the star could b…
