Physical properties and trigonometric distance of the peculiar dwarf WISE J181005.5101002.3
N. Lodieu, M. R. Zapatero Osorio, E. L. Martin +2
Our goal is to characterise the physical properties of the metal-poor brown dwarf population. In particular, we focus on the recently discovered peculiar dwarf WISE J18100551010…
Primeval very low-mass stars and brown dwarfs - IV. New L subdwarfs, Gaia astrometry, population properties, and a blue brown dwarf binary
Z. H. Zhang, M. C. Galvez-Ortiz, D. J. Pinfield +13
We present 27 new L subdwarfs and classify five of them as esdL and 22 as sdL. Our L subdwarf candidates were selected with the UKIRT Infrared Deep Sky Survey and Sloan Digital Sky…
Primeval very low-mass stars and brown dwarfs - III. The halo transitional brown dwarfs
Z. H. Zhang, D. J. Pinfield, M. C. Galvez-Ortiz +11
We report the discovery of an esdL3 subdwarf, ULAS J020858.62+020657.0, and a usdL4.5 subdwarf, ULAS J230711.01+014447.1. They were identified as L subdwarfs by optical spectra obt…
A Tale of Three Cities: OmegaCAM discovers multiple sequences in the color-magnitude diagram of the Orion Nebula Cluster
G. Beccari, M. G. Petr-Gotzens, H. M. J. Boffin +15
As part of the Accretion Discs in H with OmegaCAM (ADHOC) survey, we imaged in r, i and H-alpha a region of 12x8 square degrees around the Orion Nebula Cluster. Thanks to the hi…
SMA observations of the proto brown dwarf candidate SSTB213 J041757
N. Phan-Bao, C. -F. Lee, P. T. P. Ho +1
Context. The previously identified source SSTB213 J041757 is a proto brown dwarf candidate in Taurus, which has two possible components A and B. It was found that component B is pr…
A near-infrared variability campaign of TMR-1: New light on the nature of the candidate protoplanet TMR-1C
B. Riaz, E. L. Martin, M. G. Petr-Gotzens +1
(abridged) We present a near-infrared (NIR) photometric variability study of the candidate protoplanet, TMR-1C, located at a separation of about 10" (~1000 AU) from the Class I pro…
Glancing views of the Earth. From a lunar eclipse to an exoplanetary transit
A. García Muñoz, M. R. Zapatero Osorio, R. Barrena +3
It has been posited that lunar eclipse observations may help predict the in-transit signature of Earth-like extrasolar planets. However, a comparative analysis of the two phenomena…
Four ultra-short period eclipsing M-dwarf binaries in the WFCAM Transit Survey
S. V. Nefs, J. L. Birkby, I. A. G. Snellen +16
We report on the discovery of four ultra-short period (P<0.18 days) eclipsing M-dwarf binaries in the WFCAM Transit Survey. Their orbital periods are significantly shorter than of…
Search for radial velocity variations in eight M-dwarfs with NIRSPEC/Keck II
Florian Rodler, Rohit Deshpande, Maria Rosa Zapatero Osorio +4
Context. Radial velocity (RV) measurements from near-infrared spectra have become a potentially powerful tool to search for planets around cool stars and sub-stellar objects. As pa…
The radial distribution of dust species in young brown dwarf disks
B. Riaz, M. Honda, H. Campins +5
We present a study of the radial distribution of dust species in young brown dwarf disks. Our work is based on a compositional analysis of the 10 and 20 micron silicate emission fe…
WISE/2MASS-SDSS brown dwarfs candidates using Virtual Observatory tools
M. Aberasturi, E. Solano, E. L. Martin
Massive far-red and infrared imaging surveys in different bandpasses are the main contributors to the discovery of brown dwarfs. The Virtual Observatory represents an adequate fram…
A binary merger origin for inflated hot Jupiter planets
E. L. Martin, H. C. Spruit, R. Tata
We hypothesize that hot Jupiters with inflated sizes represent a separate planet formation channel,the merging of two low-mass stars. We show that the abundance and properties of W…
Source to Accretion Disk Tilt
M. M. Montgomery, E. L. Martin
Many different system types retrogradely precess, and retrograde precession could be from a tidal torque by the secondary on a misaligned accretion disk. However, a source to cause…
Large Amplitude Photometric Variability of the Candidate Protoplanet TMR-1C
B. Riaz, E. L. Martin
In their HST/NICMOS observations, Terebey et al. 1998 detected a candidate protoplanet, TMR-1C, that lies at a separation of about 10" (~1000 AU) from the Class I protobinary TMR-1…
Proper motion and Photometric Variability of the Candidate Propotoplanet TMR-1C
B. Riaz, E. L. Martin
In their HST/NICMOS observations, Terebey et al. 1998 detected a candidate protoplanet, TMR-1C, that lies at a separation of about 10" (~1000 AU) from the Class I protobinary TMR-1…
Magnetic Field Topology in Low-Mass Stars: Spectropolarimetric Observations of M Dwarfs
