Revisiting equilibrium condensation and rocky planet compositions: Introducing the ECCOplanets code
Anina Timmermann, Yutong Shan, Ansgar Reiners +1
We introduce ECCOplanets, an open-source Python code that simulates condensation in the protoplanetary disk. Our aim is to analyse how well a simplistic model can reproduce the mai…
A detailed analysis of the Gl 486 planetary system
J. A. Caballero, E. Gonzalez-Alvarez, M. Brady +64
The Gl 486 system consists of a very nearby, relatively bright, weakly active M3.5 V star at just 8 pc with a warm transiting rocky planet of about 1.3 R_Terra and 3.0 M_Terra that…
The HD 260655 system: Two rocky worlds transiting a bright M dwarf at 10 pc
R. Luque, B. J. Fulton, M. Kunimoto +64
We report the discovery of a multi-planetary system transiting the M0 V dwarf HD 260655 (GJ 239, TOI-4599). The system consists of at least two transiting planets, namely HD 260655…
Magnetism, rotation, and nonthermal emission in cool stars -- Average magnetic field measurements in 292 M dwarfs
A. Reiners, D. Shulyak, P. J. Käpylä +16
Stellar dynamos generate magnetic fields that are of fundamental importance to the variability and evolution of Sun-like and low-mass stars, and for the development of their planet…
The CARMENES search for exoplanets around M dwarfs: Spectroscopic orbits of nine M-dwarf multiple systems, including two triples, two brown dwarf candidates, and one close M-dwarf-white dwarf binary
D. Baroch, J. C. Morales, I. Ribas +33
M dwarfs are ideal targets for the search of Earth-size planets in the habitable zone using the radial velocity method, attracting the attention of many ongoing surveys. As a by-pr…
The CARMENES search for exoplanets around M dwarfs. Two terrestrial planets orbiting G 264-012 and one terrestrial planet orbiting Gl 393
P. J. Amado, F. F. Bauer, C. Rodríguez López +51
We report the discovery of two planetary systems, namely G 264-012, an M4.0 dwarf with two terrestrial planets ( M and $M_{\rm c…
Simultaneous photometric and CARMENES spectroscopic monitoring of fast-rotating M dwarf GJ 3270. Discovery of a post-flare corotating feature
E. N. Johnson, S. Czesla, B. Fuhrmeister +33
Context: Active M dwarfs frequently exhibit large flares, which can pose an existential threat to the habitability of any planet in orbit in addition to making said planets more di…
OGLE-2007-BLG-224L: Confirmation of Terrestrial Parallax
Yutong Shan, Jennifer C. Yee, Vanessa P. Bailey +4
We present limits on the lens flux of OGLE-2007-BLG-224 based on MagAO imaging taken seven years after the microlensing event. At the time of the observations, the lens should have…
Precise mass and radius of a transiting super-Earth planet orbiting the M dwarf TOI-1235: a planet in the radius gap?
P. Bluhm, R. Luque, N. Espinoza +78
We report the confirmation of a transiting planet around the bright, inactive M0.5 V star TOI-1235 (TYC 4384-1735-1, V = 11.5 mag), whose transit signal was detected in the photome…
OGLE-2014-BLG-0962 and the First Statistical Validation of Bayesian Priors for Galactic Microlensing
Yutong Shan, Jennifer C. Yee, Andrzej Udalski +46
OGLE-2014-BLG-0962 (OB140962) is a stellar binary microlensing event that was well-covered by observations from the Spitzer satellite as well as ground-based surveys. Modelling yie…
Obliquity Variations of Habitable Zone Planets Kepler-62f and Kepler-186f
Yutong Shan, Gongjie Li
Obliquity variability could play an important role in the climate and habitability of a planet. Orbital modulations caused by planetary companions and the planet's spin axis preces…
The Multiplicity of M-Dwarfs in Young Moving Groups
Yutong Shan, Jennifer C. Yee, Brendan P. Bowler +11
We image 104 newly identified low-mass (mostly M-dwarf) pre-main sequence members of nearby young moving groups with Magellan Adaptive Optics (MagAO) and identify 27 binaries with…
Measuring the Number of M-Dwarfs per M-Dwarf Using Kepler Eclipsing Binaries
Yutong Shan, John A. Johnson, Timothy D. Morton
We measure the binarity of detached M-dwarfs in the Kepler field with orbital periods in the range of 1-90 days. Kepler's photometric precision and nearly continuous monitoring of…
Revised Mass-to-Light Ratios For Nearby Galaxy Groups and Clusters
Yutong Shan, Michael McDonald, Stephane Courteau
We present a detailed investigation of the cluster stellar mass-to-light (M*/L) ratio and cumulative stellar masses, derived on a galaxy-by-galaxy basis, for 12 massive (M500 ~ 10^…
