Faith Hawthorn - TOI-836: A super-Earth and mini-Neptune transiting a nearby K-dwarf

# data[].attributes.body
We present the discovery of two exoplanets transiting TOI-836 (TIC 440887364) using data from TESS Sector 11 and Sector 38. TOI-836 is a bright ( T=8.5  mag), high proper motion ( ∼200  mas yr −1 ), low metallicity ([Fe/H] ≈−0.28 ) K-dwarf with a mass of  0.68±0.05  M ⊙  and a radius of  0.67±0.01  R ⊙ . We obtain photometric follow-up observations with a variety of facilities, and we use these data-sets to determine that the inner planet, TOI-836 b, is a  1.70±0.07  R ⊕  super-Earth in a 3.82 day orbit, placing it directly within the so-called 'radius valley'. The outer planet, TOI-836 c, is a  2.59±0.09  R ⊕  mini-Neptune in an 8.60 day orbit. Radial velocity measurements reveal that TOI-836 b has a mass of  4.5±0.9  M ⊕  , while TOI-836 c has a mass of  9.6±2.6  M ⊕ . Photometric observations show Transit Timing Variations (TTVs) on the order of 20 minutes for TOI-836 c, although there are no detectable TTVs for TOI-836 b. The TTVs of planet TOI-836 c may be caused by an undetected exterior planet.

# data[].attributes.body
A dozen young low-gravity planetary-mass objects have been detected recently (Zhang et al. 2021). Variability of L and T dwarfs reflects the atmospheric structures in their atmospheres and has been studied for a long time for field dwarfs (e.g., Radigan 2014a,b). Do young low-gravity objects have similar variability trends as the field dwarfs, especially for late-L and T type objects? Explore my poster!

Emma Bubb - Exploring the Variability of Cloudy Brown Dwarf Atmospheres: The Case of WISE 1049 5319 AB

# data[].attributes.body
Brown dwarfs and giant extrasolar planets display light curve variability around the L/T transition. This variability is possibly due to inhomogeneous clouds of silicate and iron condensates in the atmospheres of these objects. The presence of these patchy clouds creates a variation in the objects observed brightness as it rotates. Using a mixture of photometric methods and the Doppler Imaging technique we are studying the brown dwarf binary WISE 1049−5319 AB to gain a greater understanding of the top of atmosphere structure of these objects.

We have returned to the resolved white dwarf-brown dwarf system PHL5038AB in order to determine its orbital period and likely evolution. We determine the brown dwarf originally orbited ~30 AU from its star - similar to Neptune in our solar system. Newly discovered metal pollution of the white dwarf indicates there may be other rocky bodies present in the system as well.

Kathryn Hartley: Optimised temporal binning of comparison star measurements for differential photometry

# data[].attributes.body
Ground-based, high precision observations of the light curves of objects such as transiting exoplanets rely heavily on the application of differential photometry. The flux of the target object is measured relative to a comparison star in the same field, allowing correction for systematic trends in the light curve, mainly due to atmospheric effects including the variation of extinction with airmass. However, the precision of the light curve is then limited by the random noise for the measurements of both the target object and the comparison star. For time-resolved photometry using short exposure times of up to a few tens of seconds, in many cases the time scale of the systematic variations due to atmospheric (or other) effects may be much longer than the cadence of the observations. In this case the overall signal-to-noise ratio of the observation may be improved significantly by applying some temporal binning to the measurements of the comparison star, before comparison with the target object, without reducing the cadence of the overall light curve. We will describe a data reduction pipeline for implementing this method which optimises the number of frames to be binned for the comparison star, and we will present some example results for time-resolved photometric data.

A Grid of Non-grey General Circulation Models of Ultra-hot Jupiters

# data[].attributes.body
We present a grid of non-grey general circulation models of ultra-hot Jupiters in order to understand the physical and dynamical processes affecting their phase-curve observations. A big surprise from model-observation comparisons is that we systematically underestimate the day-night temperature differences at Spitzer bands despite that some of our models have very strong drag. This points to possibilities of even stronger magnetic dissipation or less strong optical absorption (thus less thermal inversion). Come and chat for more interesting related stuff!

Using near-infrared spectroscopy, we have discovered a new white dwarf-brown dwarf binary 218pc away. It has a separation of 207 AU making it the third closest separated white dwarf-brown dwarf binary. Using brown dwarf template spectra we determine the spectral type of the companion as L4. This poster briefly describes our methodology and highlights key results about the new white dwarf-brown dwarf binary. Come and talk to me if you're interested in knowing more about it :)

Using a method similar to CT-scans in hospitals, I have imaged two planetary debris discs around white dwarfs. This makes use of the apsidal precession these discs exhibit, combined with the radial velocity information we can obtain from their spectra which changes as the disc precesses. I give a pictorial view of our methodology and some conclusions from the second image I have produced. Come talk to me if you are interested in this, or white dwarf planetary systems in general!

I model the X-ray evaporation history of three planets (1.0, 3.0, and 1.5 Earth radii in order of orbital separation) around the 700 Myr K-dwarf K2-136.
I find that all three planets are consistent with having formed with large gaseous envelopes, and evolved to their present state due to X-ray induced evaporation, where only the middle planet (3 Earth radii) maintains a significant atmosphere.
