Efficient Follow-Up of Exoplanet Transits Using Small Telescopes

Beck, Peter; Robson, Luke; Gallaway, Mark; Jones, Hugh R. A.; Campbell, David (2019-06-21)

Here, we introduce an online tool for the prediction of exoplanet transit light curves. Small telescopes can readily capture exoplanet transits under good weather conditions when the combination of a bright star and a large ...

Automated, unsupervised inversion of multiwavelength lidar data with TiARA : Assessment of retrieval performance of microphysical parameters using simulated data

Mueller, Detlef; Chemyakin, Eduard V.; Kolgotin, Alexei V.; Ferrare, Richard A.; Hostetler, Chris A.; Romanov, A. (2019-06-18)

We evaluate the retrieval performance of the automated, unsupervised inversion algorithm, Tikhonov Advanced Regularization Algorithm (TiARA), which is used for the autonomous retrieval of microphysical parameters of ...

Search for nearby Earth analogs I. 15 planet candidates found in PFS data

Feng, Fabo; Crane, Jeffrey D.; Wang, Sharon Xuesong; Teske, Johanna K.; Shectman, Stephen A.; Díaz, Matías R.; Thompson, Ian B.; Jones, Hugh R. A.; Butler, R. Paul (2019-06-17)

The radial velocity (RV) method plays a major role in the discovery of nearby exoplanets. To efficiently find planet candidates from the data obtained in high-precision RV surveys, we apply a signal diagnostic framework ...

An ALMA survey of the SCUBA-2 Cosmology Legacy Survey UKIDSS/UDS field : Source catalogue and properties

Stach, S. M.; Dudzevičiūtė, U.; Smail, I.; Swinbank, A. M.; Geach, J. E.; An, F. X.; Almaini, O.; Arumugam, V.; Blain, A. W.; Chapman, S. C.; Conselice, C. J.; Cooke, E. A.; Coppin, K. E. K.; Cunha, E. da; Dunlop, J. S.; Farrah, D.; Gullberg, B.; Hodge, J. A.; Ivison, R. J.; Kocevski, Dale D.; Michałowski, M. J.; Miyaji, Takamitsu; Scott, D.; Wardlow, J. L.; Weiss, Axel; Werf, P. van der (2019-06-06)

We present the catalogue and basic properties of sources in AS2UDS, an 870-\mum continuum survey with the Atacama Large Millimetre/sub-millimetre Array (ALMA) of 716 single-dish sub-millimetre sources detected in the ...

Detection of Planetary and Stellar Companions to Neighboring Stars via a Combination of Radial Velocity and Direct Imaging Techniques

Kane, Stephen R.; Dalba, Paul A.; Li, Zhexing; Horch, Elliott P.; Hirsch, Lea A.; Horner, Jonathan; Wittenmyer, Robert A.; Howell, Steve B.; Everett, Mark E.; Butler, R. Paul; Tinney, Christopher G.; Carter, Brad D.; Wright, Duncan J.; Jones, Hugh R. A.; Bailey, Jeremy; O'Toole, Simon J. (2019-06-04)

The sensitivities of radial velocity (RV) surveys for exoplanet detection are extending to increasingly longer orbital periods, where companions with periods of several years are now being regularly discovered. Companions ...

Activity and telluric contamination in HARPS observations of Alpha Centauri B

Lisogorskyi, Maksym; Jones, Hugh; Feng, Fabo (2019-06-01)

The Alpha Centauri system is the primary target for planet search as it is the closest star system composed of a solar twin α CenA, a K-dwarf α Cen B, and an M-dwarf Proxima Centauri, which has a confirmed planet in the ...

The O star hinterland of the Galactic starburst, NGC 3603

Drew, J. E.; Monguió, M.; Wright, N. J. (2019-06-01)

The very bright and compact massive young cluster, NGC 3603, has been cited as an example of a starburst in the Milky Way and compared with the much-studied R136/30 Doradus region in the Large Magellanic Cloud. Here we ...

The Dynamics and Distribution of Angular Momentum in HiZELS Star-Forming Galaxies at z = 0.8 - 3.3

Gillman, S.; Swinbank, A. M.; Tiley, A. L.; Harrison, C. M.; Smail, Ian; Dudzevičiūtė, U.; Sharples, R. M.; Best, P. N.; Bower, R. G.; Cochrane, R.; Fisher, D.; Geach, J. E.; Glazebrook, K.; Ibar, Edo; Molina, J.; Obreschkow, D.; Schaller, M.; Sobral, D.; Sweet, S.; Trayford, J. W.; Theuns, T. (2019-06)

We present adaptive optics assisted integral field spectroscopy of 34 star-forming galaxies at z = 0.8-3.3 selected from the HiZELS narrow-band survey. We measure the kinematics of the ionized interstellar medium on ∼1 kpc ...

The asymptotic evolution of the stellar merger V1309 Sco: a Blue Straggler in the making?

Ferreira, Thiago; Saito, Roberto K.; Minniti, Dante; Navarro, María Gabriela; Ramos, Rodrigo Contreras; Smith, Leigh; Lucas, Philip W. (2019-06-01)

Stellar mergers are estimated to be common events in the Galaxy. The best studied stellar merger case to date is V1309 Sco (= Nova Scorpii 2008) which was originally misclassified as a Nova event. Later identified as the ...

The JCMT BISTRO Survey : The Magnetic Field of the Barnard 1 Star-Forming Region

Coudé, Simon; Bastien, Pierre; Houde, Martin; Sadavoy, Sarah; Friesen, Rachel; Francesco, James Di; Johnstone, Doug; Mairs, Steve; Hasegawa, Tetsuo; Kwon, Woojin; Lai, Shih-Ping; Qiu, Keping; Ward-Thompson, Derek; Berry, David; Chen, Michael Chun-Yuan; Fiege, Jason; Franzmann, Erica; Hatchell, Jennifer; Lacaille, Kevin; Matthews, Brenda C.; Moriarty-Schieven, Gerald H.; Pon, Andy; André, Philippe; Arzoumanian, Doris; Aso, Yusuke; Byun, Do-Young; Chakali, Eswaraiah; Chen, Huei-Ru; Chen, Wen Ping; Ching, Tao-Chung; Cho, Jungyeon; Choi, Minho; Chrysostomou, Antonio; Chung, Eun Jung; Doi, Yasuo; Drabek-Maunder, Emily; Dowell, C.
