Spectroscopic distance, mass, and age estimations for APOGEE DR17
Alexander Stone-Martinez, Jon A. Holtzman, Julie Imig +3
We derive distances and masses of stars from the Sloan Digital Sky Survey (SDSS) Apache Point Observatory Galactic Evolution Experiment (APOGEE) Data Release 17 (DR17) using simple…
Populating the brown dwarf and stellar boundary: Five stars with transiting companions near the hydrogen-burning mass limit
Nolan Grieves, François Bouchy, Monika Lendl +52
We report the discovery of five transiting companions near the hydrogen-burning mass limit in close orbits around main sequence stars originally identified by the Transiting Exopla…
Observation of a possible superflare on Proxima Centauri
John F. Kielkopf, Rhodes Hart, Bradley D. Carter +1
We report the observation on UT 2017.07.01 of an unusually powerful flare detected in near-infrared continuum photometry of Proxima Centauri. During a campaign monitoring the star…
High Resolution Spectroscopy and Spectropolarimetry of some late F-/early G-type sun-like stars as targets for Zeeman Doppler imaging
Ian Waite, Stephen Marsden, Brad Carter +4
High resolution spectroscopy and spectropolarimetry have been undertaken at the Anglo-Australian Telescope in order to identify suitable targets for magnetic studies of young sun-l…
Magnetic fields and differential rotation on the pre-main sequence III: The early-G star HD 106506
I. A. Waite, S. C. Marsden, B. D. Carter +5
We present photometry and spectropolarimetry of the pre-main sequence star HD 106506. A photometric rotational period of ~1.416 +/- 0.133 days has been derived using observations a…
Magnetic fields and differential rotation on the pre-main sequence II: The early-G star HD 141943 - coronal magnetic field, H-alpha emission and differential rotation
S. C. Marsden, M. M. Jardine, J. C. Ramírez Vélez +8
Spectropolarimetric observations of the pre-main sequence early-G star HD 141943 were obtained at three observing epochs (2007, 2009 and 2010). The observations were obtained using…
Magnetic fields and differential rotation on the pre-main sequence I: The early-G star HD 141943 - brightness and magnetic topologies
S. C. Marsden, M. M. Jardine, J. C. Ramírez Vélez +8
Spectroscopic and spectropolarimetric observations of the pre-main sequence early-G star HD 141943 were obtained at four observing epochs (in 2006, 2007, 2009 and 2010). The observ…
