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-…

NGTS-39 b: A 58 d transiting warm Jupiter in an eccentric orbit

Ioannis Apergis, Daniel Bayliss, Solène Ulmer-Moll +53

We report the discovery and characterisation of NGTS-39 b (TIC 453147896 b), a warm Jupiter transiting a Sun-like star on a 58.2 day, eccentric (e = 0.386 +/- 0.019) orbit. NGTS-39…

High-Precision Photometry with a scientific CMOS Camera: II On-Sky Testing of the Marana camera at the NGTS facility

Ioannis Apergis, Daniel Bayliss, Paul Chote +24

Modern scientific CMOS cameras offer very fast readout speeds and low read noise. In this study, we evaluate the performance of the Andor Marana CMOS camera through on-sky testing…

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-…

A 43 day transiting Neptune and two 25 day Saturns from TESS, NGTS and ASTEP

Alicia Kendall, Solène Ulmer-Moll, Samuel Gill +53

Beyond orbital periods of 10 days, there is a dearth of known transiting gas giants. On longer orbits, planets are less affected by their host star, and become ideal probes of plan…

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…

Detection and characterisation of a 106-day transiting Jupiter : TOI-2449 b / NGTS-36 b

S. Ulmer-Moll, S. Gill, R. Brahm +64

Only a handful of transiting giant exoplanets with orbital periods longer than 100 days are known. These warm exoplanets are valuable objects as their radius and mass can be measur…

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…

Viewing the PLATO LOPS2 Field Through the Lenses of TESS

Yoshi Nike Emilia Eschen, Daniel Bayliss, Thomas G. Wilson +3

PLATO will begin observing stars in its Southern Field (LOPS2) after its launch in late 2026. By this time, TESS will have observed the stars in LOPS2 for at least four years. We f…

The TESS SPOC FFI Target Sample Explored with Gaia

Lauren Doyle, David J. Armstrong, Daniel Bayliss +2

The TESS mission has provided the community with high-precision times series photometry for 2.8 million stars across the entire sky via the Full Frame Image (FFI) light curve…

TIaRA TESS 1: Estimating exoplanet yields from Year 1 and Year 3 SPOC lightcurves

Toby Rodel, Daniel Bayliss, Samuel Gill +1

We present a study of the detection efficiency for the TESS mission, focusing on the yield of longer-period transiting exoplanets ( days). We created the Transit Investigat…

TESS Duotransit Candidates from the Southern Ecliptic Hemisphere

Faith Hawthorn, Sam Gill, Daniel Bayliss +20

Discovering transiting exoplanets with long orbital periods allows us to study warm and cool planetary systems with temperatures similar to the planets in our own Solar system. The…
