TOI-7166 b: A Habitable Zone mini-Neptune planet around a nearby low-mass star

Khalid Barkaoui, Francisco J. Pozuelos, Benjamin V. Rackham +41

We present the discovery and validation of TOI-7166b, a 2.01+/-0.05R_Earth planet orbiting a nearby low-mass star. We validated the planet by combining TESS and multi-color high-pr…

TOI-1743 b, TOI-5799 b, TOI-5799 c and TOI-6223 b: TESS discovery and validation of four super-Earth to Neptune-sized planets around M dwarfs

S. Yalçınkaya, K. Barkaoui, Ö. Baştürk +62

We present the discovery by the TESS mission of one transiting Neptune-sized planet, TOI-6223 b and two transiting super-Earths, TOI-1743 b and TOI-5799 b. We validate these planet…

Chemical abundances and doppler imaging of the Ap Si/He-wk star HD 100357

Athul Dileep, Santosh Joshi, Sofya Alexeeva +11

We present the results of time-resolved photometry, abundance analysis and Doppler imaging of an Ap star, HD 100357. The {\it TESS} photometry revealed rotational modulation with a…

A transiting giant planet in orbit around a 0.2-solar-mass host star

Edward M. Bryant, Andrés Jordán, Joel D. Hartman +56

Planet formation models suggest that the formation of giant planets is significantly harder around low-mass stars, due to the scaling of protoplanetary disc masses with stellar mas…

TOI-2407 b: a warm Neptune in the desert

C. Janó Muñoz, M. J. Hooton, P. P. Pedersen +22

We present the validation of TOI-2407 b, a warm Neptune-sized planet with a radius of 4.26 0.26 R, orbiting an early M-type star with a period of 2.7 days and an equ…

TOI-6508b: A massive transiting brown dwarf orbiting a low-mass star

K. Barkaoui, D. Sebastian, S. Zúñiga-Fernández +44

We report the discovery of a transiting brown dwarf orbiting a low-mass star, TOI-6508b. Today, only ~50 transiting brown dwarfs have been discovered. TOI-6508b was first detected…

Investigating Pulsating Variables and Eclipsing Binaries in NGC 2126 using Ground and Space-based Photometry, Astrometry, Spectroscopy and Modeling

Athul Dileep, Santosh Joshi, Sneh Lata +12

Pulsating variables are prevalent in the classical δ Scuti instability strip of intermediate-age open star clusters. The cluster membership of these stars facilitates a comparative…

TOI-2015b: a sub-Neptune in strong gravitational interaction with an outer non-transiting planet

K. Barkaoui, J. Korth, E. Gaidos +119

TOI-2015 is a known exoplanetary system around an M4 dwarf star, consisting of a transiting sub-Neptune planet in a 3.35-day orbital period, TOI-2015b, accompanied by a non-transit…
