Plato benchmark stars I. The initial benchmark sample

T. Merle, P. F. L. Maxted, O. L. Creevey +22

The ESA PLATO mission aims to detect and characterise Earth-size exoplanets orbiting bright, late-type stars using high-precision photometry and asteroseismology. Precise stellar p…

UX Men: Detached Eclipsing Binary as a Benchmark Candidate

Ganesh N. Pawar, Krzysztof G. Hełminiak, Nicola J. Miller +5

We present ultra-precise fundamental parameters for the detached eclipsing binary UX Men based on 31 TESS sectors (882 d) and radial velocities from HARPS, FEROS, CORALIE, an…

Probing down to early cosmic epochs using limited redshift () optical surveys with host galaxy age and lookback time analysis

Siddharth Kasthurirangan, Meet Panchal, Aparna Joshi +1

We present a detailed analysis of AGN identification diagnostics and host galaxy evolution using optical spectral diagnostics using ESO-GOODS-S data. We employ traditional Baldwin-…

RX Gru: a short-period pre-main-sequence eclipsing binary with a distant circumbinary companion

F. Marcadon, A. Moharana, T. B. Pawar +4

We report the discovery of a new short-period pre-main-sequence eclipsing binary, RX Gru, orbited by a distant circumbinary companion. We characterized the system by analysing the…

A comprehensive study of Scuti-type pulsators in eclipsing binaries: oscillating eclipsing Algols

T. B. Pawar, A. Miszuda, K. G. Hełminiak +4

Eclipsing double-lined spectroscopic binaries hosting Scuti-type pulsators offer a unique laboratory for simultaneously constraining stellar geometry and interior structure. In…

Adding TESS to CRÉME. Light curves and masses of 300+ eclipsing binaries

Krzysztof G. Hełminiak, Ayush Moharana, Tilak B. Pawar +1

The Comprehensive Research with Echelles on the Most interesting Eclipsing binaries (CRÉME) projects was aimed to collect high-resolutions spectra of about 380 detached eclipsing b…

Formation of Compact Hierarchical Triples

Ayush Moharana, K. G. Helminiak, T. Pawar +1

Compact hierarchical triples (CHTs) are triple stars where the tertiary is in an orbit of a period less than 1000 d. They were thought to be rare but we are discovering more of the…

Comprehensive study of five candidate delta Scuti-type pulsators in detached eclipsing binaries

T. Pawar, K. G. Hełminiak, A. Moharana +4

Pulsating stars in eclipsing binaries (EBs) provide an excellent opportunity to obtain precise, model-independent stellar parameters for studying oscillations in detail. One common…

Spectroscopy of Eclipsing Compact Hierarchical Triples I

Ayush Moharana, K. G. Hełminiak, F. Marcadon +6

Eclipsing Compact Hierarchical Triples (ECHTs) are systems with the tertiary star orbiting an eclipsing binary (EB) in an orbit of fewer than 1000 days. In a CHT, all three stars e…

Constraints on Triton atmospheric evolution from occultations: 1989-2022

B. Sicardy, A. Tej, A. R. Gomes-Junior +49

Context - Around the year 2000, Triton's south pole experienced an extreme summer solstice that occurs every about 650 years, when the subsolar latitude reached about 50°. Bracketi…

Solaris photometric survey: Search for circumbinary companions using eclipse timing variations

Ayush Moharana, K. G. Hełminiak, F. Marcadon +8

Eclipse timing variations (ETV) have been a successful tool for detecting circumbinary companions to eclipsing binaries (EB). While TESS and Kepler have been prolific for ETV searc…

Pluto's atmosphere in plateau phase since 2015 from a stellar occultation at Devasthal

Bruno Sicardy, Nagarhalli M. Ashok, Anandmayee Tej +13

A stellar occultation by Pluto was observed on 6 June 2020 with the 1.3-m and 3.6-m telescopes located at Devasthal, Nainital, India, using imaging systems in the I and H bands, re…
