NGTS clusters survey - VII. An Enigmatic Short-Period Circumsecondary Disk Candidate in Orion
Niamh Mallaghan, Ernst J. W. de Mooij, Christopher A. Watson +31
Young stellar systems provide key insights into the processes governing star/planet formation, often exhibiting complex and evolving photometric variability. In this paper, we pres…
The Fe I 4377 Å Line as a Solar Faculae Indicator: Insights from Spectral Ratio Analysis
Katlyn L. Hobbs, Christopher A. Watson, Jean C. Costes +21
Faculae are a dominant source of stellar activity noise in radial velocity measurements, yet their low contrast and broad surface distribution make them difficult to track in disc-…
Spectral Ratio Analysis: probing of a new suite of stellar activity indicators as a tool for astrophysical noise mitigation
Jean C. Costes, Christopher A. Watson, Ernst de Mooij +6
Stellar activity is the main barrier to detecting and/or confirming low-mass/long-period (and Earth-analogue) planets using radial-velocity (RV) measurements. Searching for reliabl…
TIC-65910228 b / NGTS-38 b, a 180 day transiting warm super-Jupiter
Toby Rodel, Solène Ulmer-Moll, Samuel Gill +63
We present the discovery of TIC-65910228 b / NGTS-38 b, a giant exoplanet with a radius of R and a mass of M on a long-…
NGTS-EB-8: A double-lined eclipsing M+M binary discovered by citizen scientists
Sean M. O'Brien, Megan E. Schwamb, Christopher A. Watson +54
We report the identification and characterization of a new binary system composed of two near-equal mass M-dwarfs. The binary NGTS-EB-8 was identified as a planet candidate in data…
NGTS-EB-7, an eccentric, long-period, low-mass eclipsing binary
Toby Rodel, Christopher. A. Watson, Solène Ulmer-Moll +35
Despite being the most common types of stars in the Galaxy, the physical properties of late M dwarfs are often poorly constrained. A trend of radius inflation compared to evolution…
Ultraviolet Spectropolarimetry: Investigating stellar magnetic field diagnostics
C. P. Folsom, R. Ignace, C. Erba +9
Magnetic fields are important for stellar photospheres and magnetospheres, influencing photospheric physics and sculpting stellar winds. Observations of stellar magnetic fields are…
