Trends in Atmospheric Properties of Neptune-size Exoplanets
Authors: Crossfield Ian J. M. , Kreidberg Laura 
Published: November 2017

Abstract
Precise atmospheric observations have been made for a growing sample of warm Neptunes. Here, we investigate the correlations between these observations and a large number of system parameters to show that, at 95% confidence, the amplitude of a warm Neptune’s spectral features in transmission correlates with either its equilibrium temperature (T
eq) or its bulk H/He mass fraction (f
HHe)—in addition to the standard

scaling. These correlations could indicate either more optically thick, photochemically produced hazes at lower T
eq and/or higher-metallicity atmospheres for planets with smaller radii and lower f
HHe. We derive an analytic relation to estimate the observing time needed with JWST/NIRISS to confidently distinguish a nominal gas giant’s transmission spectrum from a flat line. Using this tool, we show that these possible atmospheric trends could reduce the number of expected TESS planets accessible to JWST spectroscopy by up to a factor of eight. Additional observations of a larger sample of planets are required to confirm these trends in atmospheric properties as a function of planet or system quantities. If these trends can be confidently identified, the community will be well-positioned to prioritize new targets for atmospheric study and eventually break the complex degeneracies between atmospheric chemistry, composition, and cloud properties.
The Araucaria Project: The Distance to the Fornax Dwarf Galaxy from Near-infrared Photometry of RR Lyrae Stars*
Authors: Karczmarek Paulina , Pietrzyński Grzegorz , Górski Marek , Gieren Wolfgang , Bersier David 
Published: November 2017

Abstract
We have obtained single-phase near-infrared (NIR) magnitudes in the J and K bands for 77 RR Lyrae (RRL) stars in the Fornax Dwarf Spheroidal Galaxy. We have used different theoretical and empirical NIR period–luminosity–metallicity calibrations for RRL stars to derive their absolute magnitudes, and found a true, reddening-corrected distance modulus of

mag. This value is in excellent agreement with the results obtained within the Araucaria Project from the NIR photometry of red clump stars (20.858 ± 0.013 mag), the tip of the red giant branch (

mag), as well as with other independent distance determinations to this galaxy. The effect of metallicity and reddening is substantially reduced in the NIR domain, making this method a robust tool for accurate distance determination at the 5% level. This precision is expected to reach the level of 3% once the zero points of distance calibrations are refined thanks to the Gaia mission. NIR period–luminosity–metallicity relations of RRL stars are particularly useful for distance determinations to galaxies and globular clusters up to 300 kpc, that lack young standard candles, like Cepheids.
Empirical Bolometric Fluxes and Angular Diameters of 1.6 Million Tycho-2 Stars and Radii of 350,000 Stars with Gaia DR1 Parallaxes
Authors: Stevens Daniel J. , Stassun Keivan G. , Gaudi B. Scott 
Published: November 2017

Abstract
We present bolometric fluxes and angular diameters for over 1.6 million stars in the Tycho-2 catalog, determined using previously determined empirical color-temperature and color-flux relations. We vet these relations via full fits to the full broadband spectral energy distributions for a subset of benchmark stars and perform quality checks against the large set of stars for which spectroscopically determined parameters are available from LAMOST, RAVE, and/or APOGEE. We then estimate radii for the 355,502 Tycho-2 stars in our sample whose Gaia DR1 parallaxes are precise to

. For these stars, we achieve effective temperature, bolometric flux, and angular diameter uncertainties of the order of 1%–2% and radius uncertainties of order 8%, and we explore the effect that imposing spectroscopic effective temperature priors has on these uncertainties. These stellar parameters are shown to be reliable for stars with

≲ 7000 K. The over half a million bolometric fluxes and angular diameters presented here will serve as an immediate trove of empirical stellar radii with the Gaia second data release, at which point effective temperature uncertainties will dominate the radius uncertainties. Already, dwarf, subgiant, and giant populations are readily identifiable in our purely empirical luminosity-effective temperature (theoretical) Hertzsprung–Russell diagrams.
The Prototypical Young L/T-Transition Dwarf HD 203030B Likely Has Planetary Mass
Authors: Miles-Páez Paulo A. , Metchev Stanimir , Luhman Kevin L. , Marengo Massimo , Hulsebus Alan 
Published: November 2017

Abstract
Upon its discovery in 2006, the young L7.5 companion to the solar analog HD 203030 was found to be

K cooler than older late-L dwarfs, which is quite unusual. HD 203030B offered the first clear indication that the effective temperature at the L-to-T spectral type transition depends on surface gravity: now a well-known characteristic of low-gravity ultra-cool dwarfs. An initial age analysis of the G8V primary star indicated that the system was 130–400 Myr old, and so the companion would be between 12 and 31

. Using moderate-resolution near-infrared spectra of HD 203030B, we now find features of very low gravity comparable to those of 10–150 Myr old L7–L8 dwarfs. We also obtained more accurate near-infrared and Spitzer/IRAC photometry, and we find a

color of 2.56 ± 0.13 mag—comparable to those observed in other young planetary-mass objects—and a luminosity of log(

) = −4.75 ± 0.04 dex. We further re-assess the evidence for the young age of the host star, HD 203030, with a more comprehensive analysis of the photometry and updated stellar activity measurements and age calibrations. Summarizing the age diagnostics for both components of the binary, we adopt an age of 100 Myr for HD 203030B and an age range of 30–150 Myr. Using cloudy evolutionary models, the new companion age range and luminosity result in a mass of 11

with a range of 8–15

, and an effective temperature of 1040 ± 50 K.
Malaise dans les start-up. Entre désir héroïque et anxiété créatrice
Authors: Buquet Romain , Luca Nathalie , Bouilloud Jean-Philippe 
Published: November 2017

Cet article porte sur l’anxiété des entrepreneurs du numérique, ou start-uppers, souvent présentés comme des héros modernes . Dix-neuf entretiens cliniques de type « récit de vie » ont été conduits par une anthropologue et un chercheur en gestion dans un incubateur phare de start-up parisiennes : le numa. Ces résultats exploratoires n’ont pas volonté à être généralisés et demanderaient d’être approfondis par d’autres études complémentaires. Ils montrent que ces jeunes entrepreneurs, réunis par un capital culturel et économique fort et un rejet paradoxal de la grande entreprise, construisent une identité collective par comportement mimétique marqué par une ambivalence entre peur de l’échec et investissement narcissique majeur dans leur projet. Ils sont soumis à une anxiété créatrice qui lie leur engagement et leur volonté de changer le monde.

Abstract
No vaccine exists against visceral leishmaniasis. To develop effective vaccines, we have previously reported protective role of live attenuated centrin gene–deleted Leishmania donovani (LdCen−/−) parasites through induction of Th1 type immune response in mice, hamsters, and dogs. In this study, we specifically explored the role of Th17 cells in LdCen−/−-induced host protection in mice. Our results showed that compared with wild-type L. donovani infection, LdCen−/− parasites induce significantly higher expression of Th17 differentiation cytokines in splenic dendritic cells. There was also induction of IL-17 and its promoting cytokines in total splenocytes and in both CD4 and CD8 T cells following immunization with LdCen−/−. Upon challenge with wild-type parasites, IL-17 and its differentiating cytokines were significantly higher in LdCen−/−-immunized mice compared with nonimmunized mice that resulted in parasite control. Alongside IL-17 induction, we observed induction of IFN-γ–producing Th1 cells as reported earlier. However, Th17 cells are generated before Th1 cells. Neutralization of either IL-17 or IFN-γ abrogated LdCen−/−-induced host protection further confirming the essential role of Th17 along with Th1 cytokines in host protection. Treatment with recombinant IL-23, which is required for stabilization and maintenance of IL-17, heightened Th17, and Tc17 responses in immunized mice splenocytes. In contrast, Th17 response was absent in immunized IL-23R−/− mice that failed to induce protection upon virulent Leishmania challenge suggesting that IL-23 plays an essential role in IL-17–mediated protection by LdCen−/− parasites. This study unveiled the role of IL-23–dependent IL-17 induction in LdCen−/− parasite-induced immunity and subsequent protection against visceral leishmaniasis.
Individual and interactive effects of warming and CO2 on Pseudo-nitzschia subcurvata and Phaeocystis antarctica, two dominant phytoplankton from the Ross Sea, Antarctica

Abstract. We investigated the effects of temperature and CO2 variation on the growth and elemental composition of cultures of the diatom Pseudo-nitzschia subcurvata and the prymnesiophyte Phaeocystis antarctica, two ecologically dominant phytoplankton species isolated from the Ross Sea, Antarctica. To obtain thermal functional response curves, cultures were grown across a range of temperatures from 0 to 14 °C. In addition, a co-culturing experiment examined the relative abundance of both species at 0 and 6 °C. CO2 functional response curves were conducted from 100 to 1730 ppm at 2 and 8 °C to test for interactive effects between the two variables. The growth of both phytoplankton was significantly affected by temperature increase, but with different trends. Growth rates of P. subcurvata increased with temperature from 0 °C to maximum levels at 8 °C, while the growth rates of P. antarctica only increased from 0 to 2 °C. The maximum thermal limits of P. subcurvata and P. antarctica where growth stopped completely were 14 and 10 °C, respectively. Although P. subcurvata outgrew P. antarctica at both temperatures in the co-incubation experiment, this happened much faster at 6 than at 0 °C. For P. subcurvata, there was a significant interactive effect in which the warmer temperature decreased the CO2 half-saturation constant for growth, but this was not the case for P. antarctica. The growth rates of both species increased with CO2 increases up to 425 ppm, and in contrast to significant effects of temperature, the effects of CO2 increase on their elemental composition were minimal. Our results suggest that future warming may be more favorable to the diatom than to the prymnesiophyte, while CO2 increases may not be a major factor in future competitive interactions between Pseudo-nitzschia subcurvata and Phaeocystis antarctica in the Ross Sea.
