Updated orbital monitoring and dynamical masses for nearby M-dwarf binaries
Per Calissendorff, Markus Janson, Laetitia Rodet +26
Young M-type binaries are particularly useful for precise isochronal dating by taking advantage of their extended pre-main sequence evolution. Orbital monitoring of these low-mass…
HATS-71b: A giant planet transiting an M3 dwarf star in TESS Sector 1
G. Á. Bakos, D. Bayliss, J. Bento +41
We report the discovery of HATS-71b, a transiting gas giant planet on a P = 3.7955 day orbit around a G = 15.35 mag M3 dwarf star. HATS-71 is the coolest M dwarf star known to host…
HATS-54b-HATS-58Ab: five new transiting hot Jupiters including one with a possible temperate companion
Néstor Espinoza, Joel D. Hartman, Gaspar Á. Bakos +18
We report the discovery by the HATSouth project of 5 new transiting hot Jupiters (HATS-54b through HATS-58Ab). HATS-54b, HATS-55b and HATS-58Ab are prototypical short period ($P =…
Dynamical masses of M-dwarf binaries in young moving groups: II - Toward empirical mass-luminosity isochrones
Markus Janson, Stephen Durkan, Mickael Bonnefoy +6
Low-mass stars exhibit substantial pre-main sequence evolution during the first ~100 Myrs of their lives. Thus, young M-type stars are prime targets for isochronal dating, especial…
HATS-70b: A 13 Mjup brown dwarf transiting an A star
G. Zhou, G. Á. Bakos, D. Bayliss +23
We report the discovery of HATS-70b, a transiting brown dwarf at the deuterium burning limit. HATS-70b has a mass of Mp=12.9 +1.8/-1.6 Mjup and a radius of Rp=1.384 +0.079/-0.074 R…
HATS-60b - HATS-69b: Ten Transiting Planets From HATSouth
J. D. Hartman, G. A. Bakos, D. Bayliss +27
We report the discovery of ten transiting extrasolar planets by the HATSouth survey. The planets range in mass from the Super-Neptune HATS-62b, with , to the S…
Dynamical masses of M-dwarf binaries in young moving groups: I - The case of TWA 22 and GJ 2060
L. Rodet, M. Bonnefoy, S. Durkan +48
Evolutionary models are widely used to infer the mass of stars, brown dwarfs, and giant planets. Their predictions are thought to be less reliable at young ages ( 200 Myr) and i…
Radial velocity survey of spatially resolved young, low-mass binaries
Stephen Durkan, Markus Janson, Simona Ciceri +6
The identification and characterisation of low-mass binaries is of importance for a range of astrophysical investigations. Low-mass binaries in young ( Myr) moving g…
HATS-59b,c: A Transiting Hot Jupiter and a Cold Massive Giant Planet Around a Sun-Like Star
P. Sarkis, Th. Henning, J. D. Hartman +27
We report the first discovery of a multi-planetary system by the HATSouth network, HATS-59b,c, a planetary system with an inner transiting hot Jupiter and an outer cold massive gia…
Resolving faint structures in the debris disk around TWA7
J. Olofsson, R. G. van Holstein, A. Boccaletti +51
Debris disks are the intrinsic by-products of the star and planet formation processes. Most likely due to instrumental limitations and their natural faintness, little is known abou…
HATS-39b, HATS-40b, HATS-41b, and HATS-42b: Three Inflated Hot Jupiters and a Super-Jupiter Transiting F Stars
J. Bento, J. D. Hartman, G. A. Bakos +22
We report the discovery of four transiting hot Jupiters from the HATSouth survey: HATS-39b, HATS-40b, HATS41b and HATS-42b. These discoveries add to the growing number of transitin…
HATS-50b through HATS-53b: four transiting hot Jupiters orbiting G-type stars discovered by the HATSouth survey
Th. Henning, L. Mancini, P. Sarkis +26
We report the discovery of four close-in transiting exoplanets, HATS-50 through HATS-53, discovered using the HATSouth three-continent network of homogeneous and automated telescop…
The discrepancy between dynamical and theoretical mass in the triplet-system 2MASS J10364483+1521394
Per Calissendorff, Markus Janson, Rainer Köhler +6
We combine new Lucky Imaging astrometry from NTT/AstraLux Sur with already published astrometry from the AstraLux Large M-dwarf Multiplicity Survey to compute orbital elements and…
Binaries among low-mass stars in nearby young moving groups
Markus Janson, Stephen Durkan, Stefan Hippler +5
The solar galactic neighbourhood contains a number of young co-moving associations of stars (so-called `young moving groups') with ages of ~10--150 Myr, which are prime targets for…
HATS-31b Through HATS-35b: Five Transiting Hot Jupiters Discovered by the HATSouth Survey
M. de Val-Borro, G. Á. Bakos, R. Brahm +24
We report the discovery of five new transiting hot Jupiter planets discovered by the HATSouth survey: HATS-31b through HATS-35b. These planets orbit moderately bright stars with V…
