Search for a habitable terrestrial planet transiting the nearby red dwarf GJ 1214 by Gillon, M., Madhusudhan, Nikku, Deming, D., Knutson, Heather A., Lanotte, A. A., Bonfils, X., Delrez, L., Jehin, Emmanuel, Fraine, Jonathan D., Magain, P., Demory, Brice-Olivier, Seager, Sara, Zsom, Andras, Desert, J.-M., Triaud, Amaury

“…Our analysis allows us to significantly improve the characterization of GJ 1214 b, to measure its occultation depth to be 70 ± 35 ppm at 4.5 μm, and to constrain it to be smaller than 205 ppm (3σ upper limit) at 3.6 μm. …”

Validation of the IRI-2012 model with GPS-based ground observation over a low-latitude Singapore station by Kumar, Sanjay, Siingh, Devendraa, Tan, Eng Leong, Razul, Sirajudeen Gulam, See, Chong Meng Samson

“…The IRI-2012 model electron density profile showed agreement with constellation observing system for meteorology, ionosphere, and climate (COSMIC) radio occultation (RO)-based measurements around 250 to 300 km and was found to be independent of the options for topside density profiles. …”

Assessment of the impact of FORMOSAT‐7/COSMIC‐2 GNSS RO observations on midlatitude and low‐latitude ionosphere specification : observing system simulation experiments using ensemb... by Hsu, C.-T., Matsuo, T., Yue, X., Fuller-Rowell, T., Ide, K., Liu, J.-Y., Fang, Tzu-Wei

“…The Formosa Satellite‐7/Constellation Observing System for Meteorology, Ionosphere, and Climate‐2 (FORMOSAT‐7/COSMIC‐2) Global Navigation Satellite System radio occultation (RO) payload can provide global observations of slant total electron content (sTEC) with an unprecedentedly high spatial temporal resolution. …”

Detection of the secondary eclipse of Qatar-1b in the Ks band by Cruz, P, Barrado, D, Lillo-Box, J, Diaz, M, Birkby, J, López-Morales, M, Fortney, JJ

“…A Markov chain Monte Carlo analysis was performed to model the correlated systematics and fit for the secondary eclipse of Qatar-1b using a previously developed occultation model. We adopted the prayer bead method to assess the effect of red noise on the derived parameters.…”

Properties of an Earth-Like Planet Orbiting a Sun-Like Star: Earth Observed by the EPOXI Mission by Livengood, Timothy A., Deming, Drake, A'Hearn, Michael F., Charbonneau, David, Hewagama, Tilak, Lisse, Carey M., McFadden, Lucy A., Meadows, Victoria S., Robinson, Tyler D., Seager, Sara, Wellnitz, Dennis D.

“…The light curve of a lunar transit of Earth on 29 May is color-dependent due to the Moon's red spectrum partially occulting Earth's relatively blue spectrum. The “vegetation red edge” spectral contrast observed between two long-wavelength visible/near-IR bands is ambiguous, not clearly distinguishing between the verdant Earth diluted by cloud cover versus the desolate mineral regolith of the Moon. …”

PHOTOMETRICALLY DERIVED MASSES AND RADII OF THE PLANET AND STAR IN THE TrES-2 SYSTEM by Barclay, Thomas, Huber, Daniel, Rowe, Jason F., Fortney, Jonathan J., Morley, Caroline V., Quintana, Elisa V., Fabrycky, Daniel C., Barentsen, Geert, Bloemen, S., Christiansen, Jessie L., Demory, Brice-Olivier, Fulton, Benjamin J., Jenkins, Jon M., Mullally, Fergal, Ragozzine, Darin, Seader, Shaun E., Shporer, Avi, Tenenbaum, Peter, Thompson, Susan E.

“…We measure a geometric albedo of 0.0136[superscript +0.0022] [subscript –0.0033] and an occultation (secondary eclipse) depth of 6.5 [superscript +1.7] [subscript –1.8] ppm which we combined with the day/night planetary flux ratio to model the atmosphere of TrES-2b. …”

E., Guenther, Hans Moritz, Morales-Calderon, M.

“…We find 9 variables likely to be "dippers," where texture in the disk occults the central star, and 11 likely to be "bursters," where accretion instabilities create brightness bursts. …”

A COORDINATED X-RAY AND OPTICAL CAMPAIGN OF THE NEAREST MASSIVE ECLIPSING BINARY, δ ORIONIS Aa. I. OVERVIEW OF THE X-RAY SPECTRUM by Corcoran, M. F., Nichols, Joy S., Pablo, H., Shenar, T., Pollock, A. M. T., Waldron, W. L., Moffat, A. F. J., Richardson, N. D., Russell, C. M. P., Hamaguchi, K., Oskinova, Lidia M., Hamann, W.-R., Ignace, R., Evans, N. R., Lomax, J. R., Hoffman, J. L., Gayley, K., Owocki, S. P., Leutenegger, M., Gull, T. R., Hole, K. T., Lauer, Jennifer L., Iping, R. C., Huenemoerder, David P., Naze, Y.

“…Since the fainter star, δ Ori Aa2, has a much lower X-ray luminosity than the brighter primary (δ Ori Aa1), δ Ori Aa provides a unique system with which to test the spatial distribution of the X-ray emitting gas around δ Ori Aa1 via occultation by the photosphere of, and wind cavity around, the X-ray dark secondary. …”

Voltaire et Frédéric II by Mervaud, C

Progrès et perfectibilité by Lotterie, F

“…Même si les Lumières et leurs héritiers ont le plus souvent tâché d’atténuer, voire d’occulter la force de l’hypothèque rousseauiste, la figure de l’homme perfectible s’est toujours trouvée prise dans une hésitation fondamentale entre le désir d’exaltation d’une promesse historique de progrès et le sentiment souvent aigu de la fragilité de cette promesse. …”

Towards consistent mapping of distant worlds: secondary-eclipse scanning of the exoplanet HD 189733b by de Wit, Julien, Gillon, M., Demory, Brice-Olivier, Seager, Sara

“…We find a 6σ deviation from the expected occultation of a uniformly-bright disk. This deviation emerges mainly from a large-scale hot spot in HD 189733b’s atmosphere, not from HD 189733b’s shape. …”

Computationally Efficient Optimization of Formation Flying Trajectories, with Solar Radiation Pressure, near Lagrange Points by Hettrick, Hailee E.

“…In particular, the characterization of exoplanets with Earth-like qualities requires imaging capabilities that exceed the current state of coronagraphs. An external occulter, commonly referred to as a starshade, flying in formation with a space-based telescope is a proposed solution to the aforementioned technological limitation. …”
