OGLE-2014-BLG-0319: A Sub-Jupiter-Mass Planetary Event Encountered Degeneracy with Different Mass Ratios and Lens-Source Relative Proper Motions
Shota Miyazaki, Daisuke Suzuki, Andrzej Udalski +36
We report the discovery of a sub-Jovian-mass planet, OGLE-2014-BLG-0319Lb. The characteristics of this planet will be added into a future extended statistical analysis of the Micro…
A rich population of free-floating planets in the Upper Scorpius young stellar association
Núria Miret-Roig, Hervé Bouy, Sean N. Raymond +9
The nature and origin of free-floating planets (FFPs) are still largely unconstrained because of a lack of large homogeneous samples to enable a statistical analysis of their prope…
O'TRAIN: a robust and flexible Real/Bogus classifier for the study of the optical transient sky
K. Makhlouf, D. Turpin, D. Corre +3
The scientific interest in studying high-energy transient phenomena in the Universe has largely grown for the last decade. Now, multiple ground-based survey projects have emerged t…
Rapid bursts of magnetically gated accretion in the intermediate polar V1025 Cen
Colin Littlefield, Jean-Pierre Lasota, Jean-Marie Hameury +5
Magnetically gated accretion has emerged as a proposed mechanism for producing extremely short, repetitive bursts of accretion onto magnetized white dwarfs in intermediate polars (…
Estimating fundamental parameters of nearby M dwarfs from SPIRou spectra
P. I. Cristofari, J. -F. Donati, T. Masseron +10
We present the results of a study aiming at retrieving the fundamental parameters of M dwarfs from spectra secured with SPIRou, the near-infrared high-resolution spectropolarimeter…
Characterizing microlensing planetary system OGLE-2014-BLG-0676Lb with adaptive optics imaging
Xiao-Jia Xie, Subo Dong, Yossi Shvartzvald +10
We constrain the host-star flux of the microlensing planet OGLE-2014-BLG-0676Lb using adaptive optics (AO) images taken by the Magellan and Keck telescopes. We measure the flux of…
MagAO observations of the binary microlens OGLE-2014-BLG-1050 prefer the higher-mass solution
Xiaojia Xie, Subo Dong, Wei Zhu +9
We report adaptive-optics (AO) follow-up imaging of OGLE-2014-BLG-1050, which is the second binary microlensing event with space-based parallax measurements. The degeneracy in micr…
The DES view of the Eridanus supervoid and the CMB Cold Spot
A. Kovács, N. Jeffrey, M. Gatti +119
The Cold Spot is a puzzling large-scale feature in the Cosmic Microwave Background temperature maps and its origin has been subject to active debate. As an important foreground str…
R Coronae Borealis and dustless Hydrogen-deficient Carbon stars have different oxygen isotope ratios
Viraj Karambelkar, Mansi Kasliwal, Patrick Tisserand +5
R Coronae Borealis (RCB) and dustless Hydrogen-deficient Carbon (dLHdC) stars are believed to be remnants of low mass white dwarf mergers. These supergiant stars have peculiar hydr…
Peculiar Hydrogen-deficient Carbon Stars: Strontium-Rich Stars and the s-Process
Courtney L. Crawford, Patrick Tisserand, Geoffrey C. Clayton +1
Context: R Coronae Borealis (RCB) variables and their non-variable counterparts, the dustless Hydrogen-Deficient Carbon (dLHdC) stars have been known to exhibit enhanced s-processe…
Detecting primordial features with LISA
Jacopo Fumagalli, Mauro Pieroni, Sébastien Renaux-Petel +1
Oscillations in the frequency profile of the stochastic gravitational wave background are a characteristic prediction of small-scale features during inflation. In this paper we pre…
BEBOP III. Observations and an independent mass measurement of Kepler-16 (AB) b -- the first circumbinary planet detected with radial velocities
Amaury H. M. J. Triaud, Matthew R. Standing, Neda Heidari +30
The radial velocity method is amongst the most robust and most established means of detecting exoplanets. Yet, it has so far failed to detect circumbinary planets despite their rel…
BEBOP II: Sensitivity to sub-Saturn circumbinary planets using radial-velocities
Matthew R. Standing, Amaury H. M. J. Triaud, João P. Faria +14
BEBOP is a radial-velocity survey that monitors a sample of single-lined eclipsing binaries, in search of circumbinary planets by using high-resolution spectrographs. Here, we desc…
Near-infrared transmission spectrum of TRAPPIST-1 h using Hubble WFC3 G141 observations
A. Gressier, M. Mori, Q. Changeat +4
The TRAPPIST-1 planetary system is favourable for transmission spectroscopy and offers the unique opportunity to study rocky planets with possibly non-primary envelopes. We present…
Galactic Star Formation with NIKA2 (GASTON): Evidence of mass accretion onto dense clumps
A. J. Rigby, R. Adam, P. Ade +49
High-mass stars () play a crucial role in the evolution of galaxies, and so it is imperative that we understand how they are formed. We have used the New…
A spectroscopic follow-up for Gaia19bld
E. Bachelet, P. Zielinski, M. Gromadzki +11
Due to their scarcity, microlensing events in the Galactic disk are of great interest and high-cadence photometric observations, supplemented by spectroscopic follow-up, are necess…
Single-lens mass measurement in the high-magnification microlensing event Gaia19bld located in the Galactic disc
K. A. Rybicki, Ł. Wyrzykowski, E. Bachelet +66
We present the photometric analysis of Gaia19bld, a high-magnification () microlensing event located in the southern Galactic plane, which exhibited finite source and m…
Gravitational waves from dark matter isocurvature
Guillem Domènech, Samuel Passaglia, Sébastien Renaux-Petel
The primordial fluctuations on large scales are adiabatic, but on smaller scales this need not be the case. Here we derive the general analytical framework to compute the stochasti…
Cosmological test of local position invariance from the asymmetric galaxy clustering
Shohei Saga, Atsushi Taruya, Michel-Andrès Breton +1
The local position invariance (LPI) is one of the three major pillars of Einstein equivalence principle, ensuring the space-time independence on the outcomes of local experiments.…
