Research & Publications
Open Science Initiative · www.qrcl.net
QRCL Technologies OÜ conducts open research in exoplanet detection, multi-messenger astronomy, and post-quantum verification systems. Our work focuses on Transit Timing Variation (TTV) analysis for hidden planet discovery, atmospheric biosignature detection methodology, and systematic frameworks for validating observational predictions.
All research publications are released under open-access principles with SHA-256 verified evidence, reproducible analysis pipelines, and publicly available datasets. We collaborate with global astronomy archives including NASA MAST/TESS/Kepler, ESA Gaia/CHEOPS, SIMBAD TAP, and the European Open Science Cloud (EOSC) EU Node to ensure transparent, verifiable science.
Our methodology emphasizes statistical rigor, cross-instrument validation, and community reproducibility. Each prediction includes confidence intervals, detection methodology documentation, and clear criteria for observational confirmation. Research collaborations and data sharing inquiries are welcome from the global astronomy community.

PUBLISHEDExoplanet Habitability Assessment: A Quantitative Analysis of 1,426 Habitable Zone Candidates from the NASA Exoplanet Archive
QRCL Research Team — QRCL Technologies OÜ (2026)
Comprehensive quantitative analysis of 1,426 exoplanets within the habitable zone (200–400 K). Multi-parameter scoring algorithm evaluates temperature (35%), radius (20%), insolation (15%), stellar type (15%), and distance (15%). Identifies one very high probability candidate (K2-3 d, P=0.758, 305 K, 1.46 R⊕), 53 high probability candidates (0.5≤P<0.7), and 97 moderate probability candidates (0.3≤P<0.5). Includes analysis data, scoring framework, and NASA Exoplanet Archive integration.
PUBLISHEDMulti-Messenger Framework for Exoplanet Biosignature Detection: Bayesian Evidence, False-Positive Rejection, and TTV Context
QRCL Research Team — QRCL Technologies OÜ (2026)
Journal-format (AASTeX 6.31) open-source pipeline integrating JWST transmission spectroscopy (NIRSpec + MIRI LRS), TESS SPOC TTV O–C residuals, ESA Gaia DR3 stellar astrometry, and N-body dynamical stability into a unified Bayesian log-evidence framework. Detection thresholds: tentative (Z>3), strong (Z>5), definitive (Z>10 dual-band + abiotic rejection). Applied to TRAPPIST-1 d/e, K2-18 b (DMS Z≈3.5, tentative), TOI-700 d/e, LHS 1140 b, Kepler-186 f.

PRELIMINARYTRAPPIST-1 d/e Transit Timing Variations: TESS SPOC-Only Refinement
QRCL Research Team — QRCL Technologies OÜ (2026)
O–C residuals from TESS SPOC light curves for TRAPPIST-1 d and e. TRAPPIST-1 d: 4 transits, O–C −59.6 to +122.4 min (stdev 71.5 min). TRAPPIST-1 e: 4 transits, O–C −37.0 to +100.6 min (stdev 56.4 min). Residuals consistent with inter-planetary gravitational perturbations. 20+ transits required before period extraction.
