Discovery of an Edge-on Circumstellar Debris Disk around BD+45 598: A Newly Identified Member of the β Pictoris Moving Group Open
We report the discovery of a circumstellar debris disk viewed nearly edge-on and associated with the young, K1 star BD+45 598 using high-contrast imaging at 2.2 μm obtained at the W.M. Keck Observatory. We detect the disk in scattered ligh…

Reinvestigation of the Multiepoch Direct Detections of HD 88133 b and Upsilon Andromedae b Open
We reanalyze the multiepoch direct detections of HD 88133 b and ups And b that were published in Piskorz et al. (2016) and Piskorz et al. (2017), respectively. Using simulations to attempt to reproduce the detections, we find that with the…

Primary Velocity and Orbital Phase Effects on Planetary Detectability from Small Epoch Number Data Sets Open
Cross-correlation analyses of high-resolution spectroscopic data have recently shown great success in directly detecting planetary signals and enabling the characterization of their atmospheres. One such technique aims to observe a system …

Contrast and Temperature Dependence of Multi-epoch High-resolution Cross-correlation Exoplanet Spectroscopy Open
While high-resolution cross-correlation spectroscopy (HRCCS) techniques have proven effective at characterizing the atmospheres of transiting and nontransiting hot Jupiters, the limitations of these techniques are not well understood. We p…

Simulating the Multi-epoch Direct Detection Technique to Isolate the Thermal Emission of the Non-transiting Hot Jupiter HD187123b Open
We report the 6.5 σ detection of water from the hot Jupiter HD187123b with a Keplerian orbital velocity K p of 53 ± 13 km s −1 . This high-confidence detection is made using a multi-epoch, high-resolution, cross-correlation technique, and …

Ground- and Space-based Detection of the Thermal Emission Spectrum of the Transiting Hot Jupiter KELT-2Ab Open
We describe the detection of water vapor in the atmosphere of the transiting hot Jupiter KELT-2Ab by treating the star–planet system as a spectroscopic binary with high-resolution, ground-based spectroscopy. We resolve the signal of the pl…

Setting the Standard: Recommendations on "Launch Unit" Standard SmallSat Sizes between CubeSats and ESPA-Class Open
Over the next ten years, more than 6000 SmallSats are expected to launch worldwide, an over six-fold increase from the previous decade. As the SmallSat market grows, launch remains the primary bottleneck to timely and affordable access to …

EVIDENCE FOR THE DIRECT DETECTION OF THE THERMAL SPECTRUM OF THE NON-TRANSITING HOT GAS GIANT HD 88133 b Open
We target the thermal emission spectrum of the non-transiting gas giant HD 88133 b with high-resolution near-infrared spectroscopy, by treating the planet and its host star as a spectroscopic binary. For sufficiently deep summed flux obser…

THE TRENDS HIGH-CONTRAST IMAGING SURVEY. VI. DISCOVERY OF A MASS, AGE, AND METALLICITY BENCHMARK BROWN DWARF Open
The mass and age of substellar objects are degenerate parameters leaving the evolutionary state of brown dwarfs ambiguous without additional information. Theoretical models are normally used to help distinguish between old, massive brown d…
